There's indeed some confusion at Blizzard's.. the SC2 client was already saying weeks ago that the lock should have been the 23rd, and the end of the season at the end of the month.

Still, here it is the Blizzard's article saying otherwise, to everyone's puzzlement: http://eu.battle.net/sc2/en/blog/14502317/2014-season-2-lock-incoming-23-06-2014

Yes. It means they forgot to update the game servers. The lock period started automatically at the original date which is visible via game client. Now it remains to be seen how they will fix it.

Copy paste from the previous page:
2014-06-23: New DB file has been published (v. 18.4) due ladder lock period. Please restart Sc2gears to download it
See details: http://www.teamliquid.net/forum/viewpost.php?post_id=22433809

!!! If you see your bonus pool start growing again, please inform it to this thread !!! It is possible that Blizzard makes in-game changes and releases the lock to correspond Psione's post. If that happens I have to update the DB file again or otherwise the calculations become incorrect.

Edit: Blizzard has acknowledged that they are investigating: http://us.battle.net/sc2/en/forum/topic/13204040595#13
They have also deleted both news posts regarding ladder lock starting one week from now from both NA & EU websites.

Edit 2: Blizzard decided that the ladder will remain locked for 2 weeks: http://us.battle.net/sc2/en/forum/topic/13243434219

2014-07-07: New DB released (v 18.6. Locks data due season switch)

EU, KR, SEA and CN servers should have now switched to season 19. I released a DB that locks data for all servers (no good games, data is used for estimate games). In a few days when Blizzard has updated all web profiles to new season (S19) I will solve bonus pool accumulation start times & release the lock.

Please restart Sc2gears to download the DB. EU, KR, SEA and CN players should update the DB immediately. NA players can optionally wait until NA server switches to new season before restarting sc2gears to download the new DB.

--
Edit 1: Web profiles for some servers have partially been updated (SEA & KR). But they are facing the same problem that occurred at the start of last season. The remaining bonus pool number is randomly either given or not available. Last time it took several days for them to fix this issue. It is a major issue as the DB has to be kept locked until it is solved.

Edit 2 (2014-07-08 01:18 CEST): Blizzard has partially updated the web profiles for all servers, but the data is affected by the missing bonus pool issue. Last time it took Blizzard 3 to 4 days to fix it. I hope they manage to fix it quicker this time. Before that I cannot release the DB lock. This means that new game data will be marked as 'bad', but it can be used as estimate data. Later when I am able to release the DB lock, I will notify it in this thread. Example polling results (once per 6 to 10 sec):

It seems like the platinum threshold for EU is a bit off. It's centered on 700, but at the end of last season I got to Platinum from Gold at around 650, went up a bit, then down again, then got demoted at first game this season, and went Plat again at around 650 (again). I think you can actually check my data for details on the server (right?).

If I remember correctly the set plat threshold should be close. It is always possibility that your last 'good' MMR calculation result was slightly off (all 'good' calculations have error margin which is shown in analyse tab) and/or your MMR has changed in later estimate games more than typical amount (but like you can see the estimates are often quite accurate as the promotion happened in about same place).

We will have to wait and see when new results from this season are available. But it may take awhile, because Blizzard has messed up once again with the web profile updates. Now the web profiles are partially updated to new season on all servers, but the bonus pool data is often missing. Last season it took them 3 to 4 days to fix it. Hopefully they manage to fix it faster this time (before that I cannot unlock the DB --> new game data can only be used as estimate data).

2014-07-08 19:55 CEST: Randomly missing bonus pool issue continues. The DB will remain locked until Blizzard fixes the web profiles. When DB is locked new match data is set 'bad', but can be used as estimate data. I will notify in this thread when it is possible to unlock the data. Last season it took them several days to fix similar issue.

The missing bonus pool issue seems to be caused because some Bnet services/servers still think the last season is the current season. In ladder division page the bonus pool is only shown if the division is from the current season. What makes this problematic is that also 0 remaining bonus pool is shown in same way (data is left empty). Thus when the bonus pool data is empty, you cannot be sure if it means 0 bonus pool or if the data is missing.

This (some services think last season is current season) became evident when I observed a profile that had been diamond during S18 and now gold in S19. Every time his profile's icon border represented this season (gold) his remaining bonus pool was shown. Every time it had diamond border (last season) his bonus pool was missing. I then checked his last season's division page. Every time when his icon border was diamond (last season) his last season's remaining bonus pool was shown. When the icon border was gold (this season) his last season' bonus pool was not shown.

Thus it seems the bonus pool issue will continue until all services have been updated to the new season.

--
Of course based on this new information few new special case consistency checks could be added. For example if the player's icon border represents different league than he is currently placed in, the bonus pool data can be considered incorrect (of course WoL data might affect the borders too). But if the player was in same league in the previous season too, then there is no way to be sure if the empty bonus pool data means 0 bonus points left or if the data is missing.

--
Edit 1 (2014-07-09 10:50 CEST): It seems Blizzard has potentially fixed the web profiles for all servers regarding the bonus pool issue. At least I am getting consistent readings without any errors at the moment. But I will wait until EU evening before updating the DB, in case of things could change.

2014-07-09: The DB file (v 19.1) has been unlocked for the season 19 (s3/2014).

Now as web profiles have been updated to S19, a DB file that unlocks the data has been released (new MMR calculation results are possible). Please restart sc2gears to download the new DB file.

Once again there was some web profile problems regarding the season switch on Blizzard's side (e.g. missing bonus pool data issue). But now the necessary basic data seems ok. But the out-of-sync web profile update issue that emerged during February has likely still not been fixed (as a result data errors that cause incorrect MMR calculation results happen more frequently).

Also note that during this year Blizzard has updated league thresholds / offsets couple of weeks after the start of each season. If they follow the same schedule the offset updates might happen between 24th and 25th of July (or one week after that).

Based on the uploaded data you use old version of the tool (v. 10.2, current version is 10.3). You can see the version number at the beginning of the main log (log button in top toolbar).

If the update button does not work for you for an unknown reason, you can also update the tool manually. 1) Close Sc2gears 2) Download the zip package that contains the tool from http://skeletor.jimmeh.com/mmr/MMRPlugin.zip and then 3) unpack its contents to [PATH_TO]\Sc2gears\Plugins\ 4) restart sc2gears

But there was no considerable changes between versions 10.2 and 10.3 except the archiving of old games. You need to play more. Please also note that games played after the start of this season and before you updated the DB earlier today were marked 'bad' (no good readings were possible). But now as the DB has been unlocked it is possible to get good calculation results from the new matches. Only thing you can do to improve your chances to get good readings is to have memory reader enabled. Else is based on luck whom you are matched against (your MMR is calculated from your opponents' data and there are lots of conditions that have to be met to be able to calculate it) & if the web profiles are updated promptly.

Edit: There are two kinds of updates: 1) DB files that are downloaded automatically when the sc2gears is launched, 2) the tool itself. If there is new version available the 'Download new version' button appears at the top toolbar and you need to press it or update the tool manually.

Edit 2: You can read when you are likely to get 'good games' e.g. from here (please note that the current league thresholds/offsets are different than the ones in the examples): http://www.teamliquid.net/forum/viewmessage.php?topic_id=334561&currentpage=162#3226

2014-07-14: Update regarding initial GM entry thresholds for S19

Traditionally I have set the GM thresholds in the tool based on GM users who played close to GM opening time for each server. Last season there were no GM users who played close enough GM opening and/or the data was not good enough to calculate the initial MMRs (or I did not trust it as data errors are possible due out-of-sync web profile updates). But as the MMR levels of GM users & their opponents who played later during the season seemed to roughly match the old thresholds I did not make any changes for a while (Last changes were made early January based on S17 initial values). I later scaled the old values to match the offset changes that Blizzard did 2014-01-24 and 2014-05-01.

Thankfully for season 19 there has been several NA GM level users who were active close to the GM opening.

For NA the old GM value was 1940. For S19 several players were promoted to GM with values ranging from 1800 to 1850. One GM account suggests even lower value between 1750 and 1800. I think I will set NA GM threshold to ~1780. These are very low values for GM (master threshold is 1410). I wonder has the NA top become so thin or is the NA top less active and as result the MMR decay has decreased the general MMR levels for them.

For EU the old value was 2210. Disappointingly I did not get clear GM threshold values for EU. However the data suggests that the threshold has likely been at least 2000 (likely higher, there are some opponents who were before GM opening around 2100 and later made it, but post GM opening there has been plenty opponents between 2000 and 2100 who did not make it). Thus EU threshold has not 'crashed down' like the NA threshold. I will continue using the old value (or drop it slightly) for EU unless I get better data in the coming days.

For Kr, Cn and Sea there has been no GM level users active this season, so I will likely use the old values for those servers. Old values are KR 2020, Cn 1720, Sea 1720.

I will not make these changes immediately, but monitor the data for some time before making the decision for the new GM threshold values. It is worth to remember that true GM thresholds are dynamic. The purpose of the static GM thresholds in the tool is to give approximation what the threshold was when the GM league opened each season (the threshold usually rises when there are less spots available). For other leagues the thresholds are static also on Blizzard's side.

To get more detailed data regarding the GM ranges, I hope more new GM level players would start using the tool in the future as many of the older GM level users have become less active these days.

--
Edit 2014-07-20: I checked the data again yesterday. The EU GMs and masters start mixing around 2070. I think I will drop the EU GM threshold to ~2100. It should be fairly close to what the initial entry threshold has been. Will update the DB file in near future regarding this & NA GM entry threshold. Also noticed that MMR of few NA GMs had already dropped to low master range (probably boosted accounts or MMR abuse).

I can connect to the profiles manually idk why sc2gears is having trouble.

Edit: I just allowed it through my firewall just to be safe even though it was successfully connecting to the online profiles once or twice but when that happened the profiles would update too late or the bonus pools would be off.

I've also been restarting sc2gears a few times so it should be up to date and it says it's on 10.3

Reason why you have been still been getting 'FatalError WEBGRABBER could not fetch season number! EXPECTED: 19' is that you use Diablo 3 RoS CE icons. The SC2 Web API breaks always when Blizzard introduces new icons. Usually they fix it in couple of weeks after the icon introduction. This time they have not fixed it even if has already been months since RoS was launched.

At start of last season Blizzard hid season numbers from the web profiles leaving the API the only way to solve it (the MMR tool tries primarily to solve the season via web profiles and if that fails it uses API). For some of your games it has used the correct season number because of it has been read successfully from your opponents' data (early season some of the opponents are playing placement matches and many have not yet played ranked and thus they don't yet have ranked web profiles. Later during the season most opponents will have ranked profiles), even if your own has failed every time. These games (season solved from opponents' data and failed for you) can provide good MMR calculation results for you, but never for your opponent, if other conditions are also met. Worth noting is that during early season many have not reached their typical adjusted point levels even at high ranges of different leagues (they gain boosted amount of points and lose less) and thus MMR cannot often be calculated based on their data.

To solve your problem switch your profile icon to non-RoS icon. And as you now have more direct communication channels with B (congrats), you might want to mention that the API fails for players using RoS icons to them (all servers). The API has other incorrect data at the moment too (at least EU and NA servers, likely others too but I did not check). For example the main API pages still gives win & game counts from the last season, even if the season number claims the counts are from this season. It is a shame that they left their API project unfinished (in my eyes). The web profiles often provide more data than the API. I only use API in cases where the data is not available from web pages: 1) solving ladder division ID (for China using the API is the only way to separate HotS & WoL divisions, for other servers if the API fails the tool solves the IDs based on web profiles), 2) solving the ladder season if the season number is not available from the web profiles (Blizzard removed the season numbers from the web profiles at start of last season (s17 / s2 2014). This might also have been done accidentally as similar has happened during some earlier seasons, but that time they fixed it later).

If you wish you can check the error message API gives for you from http://us.battle.net/api/sc2/profile/2586985/1/KillerofGods/ When you have changed your icon it should give the correct data.

What about a short explanation - TEXT - about what this mmr is doing for you in sc2 gears, why you do it, for what do we need it, etc. Just basics. An introduction. I read through so many documentation of sc2 gears but there is rarely explanation. For example for the mouse printer I found a few forum posts from 2011 about how it might be useful, later I had to ask myself and now have only a jist of how it's useful to me (just an example).

The automated matchmaking in SC2 is based on hidden values that are called as matchmaking ratings (MMR). The tool is for calculating your relative 1v1 MMR and tracking it.

We have always know in the past that league means nothing when it comes to match making, and everything is decided by the MMR only. However, I have come to suspect that, even if this is obviously still real, your actual opponent is more likely to be chosen among your same league...

I say this because in the recent months I have done a lot of win/lose streak:

- didn't get a single platinum till I got into platinum (only gold)
- only got platinums since then, but I never actually skyrocket my MMR into high platinum... I was still in the gold/platinum division line
- now I am incurring a long lose streak, and I have the MMR of a low gold, and STILL I get only platinum opponents

The exception were very very few: I think just a diamond, and a couple of silvers in around tens of games.

I think this started happening since the blocked the possibility of losing your league in mid season.. could even be that the game now refuses to give you a very low MMR opponent if you sink your own MMR, and only gives you low MMR people of your same league (until you lose leagues at the beginning of the next seasons)? I feel it high unlikey, but at least it seems, as said, that your opponent are now more likely to come from your same league..

I could be wrong, but I have never seen something like that in the past, and I play since the beta of WoL.. nobody else have noticed something similar?

We have always know in the past that league means nothing when it comes to match making, and everything is decided by the MMR only. However, I have come to suspect that, even if this is obviously still real, your actual opponent is more likely to be chosen among your same league...

Since HotS was launched it is still matching based on MMR, but there seems to be a league preference (people with similar MMR from your own league are preferred rather than people from other leagues with similar MMR). E.g. if you are in platinum league, but your MMR is in gold league range and amongst available opponents there is a platinum player who has close MMR to yours, it picks rather him than a gold player who has similar MMR (of course this has to be top down: E.g. if there is no available plat opponents with similar MMR for you, it picks a lower league opponent, even if the lower league player has plenty of possible opponents with similar MMR from his own league available).

This was quite clear especially last summer/early fall (2013) when people who had faced full MMR decay in mid-season were still mainly matched against people from their own league (others who had faced decay or who had lost enough). Opponents from lower leagues started considerably increase only close to the lower border of the lower league. Thought this has not been as clear cut during last few seasons as it was earlier. This might be due that general activity of the players has probably decreased (still the total numbers of accounts playing their placement match has not considerably decreased) or might be adjustments to the matchmaker.

One can speculate why this change was put in place. One reason might be that they wanted to hide the MMR decay feature and thus made this change. Without the change many players would have immediately noticed that their MMR had changed as after their hiatus they would have "magically" started facing people from the lower league that they were not matched against before. They evidently (e.g. conveniently forgot to mention it when they released FAQ regarding ladder changes & it took several months for them to admit it) wanted to keep the MMR decay hidden, but it is a different matter if that is related to this.

I say this because in the recent months I have done a lot of win/lose streak:

- didn't get a single platinum till I got into platinum (only gold)
- only got platinums since then, but I never actually skyrocket my MMR into high platinum... I was still in the gold/platinum division line
- now I am incurring a long lose streak, and I have the MMR of a low gold, and STILL I get only platinum opponents

Also keep in mind that lots of players who may have been inactive and faced MMR decay return when a new season starts. Even if you have kept your old MMR the general opponent level may increase. As a result you start losing more games than your win and your MMR drops naturally.

The MMR decay is harsh. Maximum decay matches roughly 20 straight losses. I keep wondering what was their logical reasoning when they reached decision to implement such harsh decay to a game where considerable portion of the player population goes inactive from time to time and as result faces decay directly (the active population faces it indirectly). As a result general MMR levels keep dropping and Blizzard is in a loop where they have to adjust the league offsets / thresholds regularly to compensate. And this only fixes the league distribution, but does not address the fact that MMR does not anymore reflect the skill for lots of players. --> Even if the matchmaker is technically working properly, the matchmaking results are often not good.

This year they have changed the league offsets / thresholds once per season. If they follow their last season's schedule, the next offset changes are expected next Thursday or Friday (24th or 25th of July).

This change has been mentioned several times in this thread and in MMR decay thread: http://www.teamliquid.net/forum/starcraft-2/429734-ladder-deflation-and-mmr-decay Last year I was considering adding some graphical examples regarding this from some players, but in the end I probably did not do it. I have not put much effort looking at this change. Last year opponents for many accounts were almost clear cut regarding this. Last time I spent some time specifically looking at this was early this year.

Edit: I seem to have given a personal example (not the several examples from others that I originally planned): http://www.teamliquid.net/forum/viewpost.php?post_id=20658852 Thought keep in mind that those days the size of the MMR range was nearly similar for different leagues (except master & gm). Nowadays some leagues as much larger than others regarding their MMR range.

I use this tool every time I play. It's helpful to view my MMR as I'm playing SC2, mainly so I don't get so frustrated when I'm getting my ass kicked. haha. It's easy to setup. It plugs right into SC2gears and uploads my games right to ggtracker where I can perform further analysis around my spending skill.

I wonder if there are any plans on porting this to scelight?

Here is one answer that I wrote couple of months ago. The Blizzard's web profiles still have issues. Last season it took more time than I would have preferred to collect enough data to solve the offsets with reasonable effort. Now I am waiting if and when Blizzard changes the offsets next time (if they follow their last season's schedule it may happen this week's Thursday/Friday). At the moment Sc2gears is simply better option for the MMR tool than Scelight:

Scelight and Sc2gears are separate programs. At the moment the plugin only supports the latest Sc2gears, but does not support Scelight.

This may change in the future. At the moment I haven't had time for porting and there are lots of open questions that need to be negotiated. For example the Scelight has a paywall. Users who have not purchased Scelight license have no auto-start feature. Due to that lots of users would forget to start Scelight during the 15 sec wait time. It is already a problem with Sc2gears that users forget to start Sc2gears which leads to lost data. With Scelight lots of more data would be lost as it is not enough just to start it. Time will tell if porting other replay parsers than Scelight needs to be considered in the future.

Data quality is very important regarding the MMR tool. Blizzard just changed the league offsets / thresholds. To be able to calculate new offsets lots of good quality data is needed. At the moment Scelight would be a downgrade compared to Sc2gears as it would lead to lost data. At the moment there are other things affecting the data quality too. Blizzard's web servers are suffering from out-of-sync updates that cause data errors regarding the match data. Coping with that is already problematic.

But in the future when I have time for developing new features, the open questions (there are more) regarding potential Scelight port will be discussed.
