For example folders under 'program files' have write restrictions). Also if you have accidentally removed write rights from that certain file you can find it from: [PATH_TO]\Sc2gears\Plugins\MMRPlugin\ The file name is 'mem.txt'. You can delete that file. When the sc2gears is started for the next time, it should recreate that file, if it has write rights. The memory reader is separate little application. The MMR plugin writes memory addresses to text file, which the mem reader then reads. It uses this information to read 4 small memory slices from the system memory, which contain 1) player's nickname, 2) player long Bnet account ID, 3) opponent's nickname, 4) opponent's long Bnet account ID. It then writes this data into a text file, which the MMR tool reads & based on that data it fetches data from both players' Bnet web profiles. If there is no write rights in that certain directory, then the memory reader does not work as supposed to. If somebody wants to check the contents of the memory read, you can check file called 'out.txt'. It is located in the same folder as 'mem.txt' (see the folder location from earlier text section). Edit: Clarified that the 'mem.txt' file can be deleted if neccessary. Do not delete the whole folder  | ||

SC2Gears is a Java program and Linux has its own Java JRE (and I do have it installed) - that's what I use to launch SC2Gears and that part works. My problem is with enabling the MMR plugin, not with starting SC2Gears itself. I had the same issue (Arch Linux amd64). Wine is the way to go. | ||

Not sure if it's an indication of something wrong, or if it's just due to error margins and very favored/unfavored matches. + Show Spoiler + Thanks for posting this. It seems that everything is still ok. Most of the opponents of the 'good games' were from same league as you. Thus those results are comparable. But the second last was against opponent from master league and his change points were larger than typical change points. It could be slight offset inaccuracy & slight inaccuracy with higher change point results (error margin for these is also larger). For example if that result is set to bad the graph looks 'natural' from that part. And as always there can be several reasons (small inaccuracies such as losses often give slightly higher result than wins, error margins, etc) that in combination make certain parts of the graph look slightly erratic. Also like you speculated some of the opponents indeed had considerably higher / lower MMR after which your MMR seemingly increased / decreased more than typical. As it has been 3 weeks since the start of the season, I checked the offset calculations. Results look mostly the same as previous 2 seasons. Thought platinum-diamond results suggest that that offset might be slightly larger than the currently used. Then again there is limited amount of plat-diam offset calculation results. Also I originally fine-tuned lots of offsets to be slightly smaller than the results suggested. Also it is unlikely that Blizzard would have touched only one offset if there were changes --> Offsets are likely the same as two previous seasons. Last season I tested out offsets which were ~10 points larger than the currently used ones, but decided that so small fine-tunes are not necessary, as the current values give good enough calculations & offsets are in sync with other offsets. Also if you fine-tune only one offset, it may break the "balance" with others (takes lots of effort to verify that all ranges are ok after making such changes). | ||

Also, has the MMR decay affected the tool at all? MMR cannot be calculated from every match (you need so called 'good game'). Your opponent's MMR is calculated from your data, your MMR is calculated from the opponent's data. Sometimes neither can be calculated, sometimes the other can be calculated and sometimes both can be calculated. When your opponent's MMR could not be calculated it is set to be 10 more than yours just to make it easier to separate the 'match dots'. Also if you hover your mouse over the opponent's dot, it says 'unknown', if opponent's MMR could not be calculated. And yes. The tool can calculate the MMR also after the decay. First 'good game' after the decay will fix the MMR to the decayed level. Also the tool has had part to play understanding how the decay works. I saw its symptoms already during the first two HotS seasons, but could not deduct the cause. When in the beginning of the previous season (S15, current season is S16) it became certain based on the data collected by the tool that there was a decay mechanism, I informed about it in this thread. You can find links to couple of example MMR graphs that show the decay from this post: http://www.teamliquid.net/forum/viewpost.php?post_id=19681312 | ||

Thanks alot for all the work you have done on this plug-in. With the release today of scelight (the succesor to sc2gears) will we see the release of a compatible version of the MMR calculator?? Thanks in advance | ||

The successor shows potential but is still missing lots of features that I personally prefer. Also it is still missing plugin API. It will likely take time before the successor is mature enough (adding support will then be considered). Also the successor's delayed launch feature for non-paying users is problematic. I am sure lots of current MMR tool users just launch sc2gears and start playing. With the successor most users would need to launch it, then wait 15 seconds and remember to push start button. If they forget, the plugin would not record anything. It is already with current plugin somewhat a problem that lots of users forget to start sc2gears before starting their laddering session. Due to this many have missing games that cause that estimate MMR near these gaps is incorrect. | ||

The MMR tool depends on a large user base for accurate calculation of league offsets. If support for sc2gears stops some time in the future and scelight is annoying to use if you don't pay I'm worried that the user base will shrink.I guess you'll just have to rewrite MMR tool to be independent. ;-) | ||

There are other replay parsers available too and the tool already is mostly separate entity. And yes there is nice synergy between MMR tool & sc2gears. Both bring users to each others. When the successor is mature enough (e.g. when there is API + certain features become more mature) you can be sure there will be talks if there is some way to overcome the mentioned problem & how much effort it takes to port MMR tool to the successor. But the decision what to do will not be made today (will certain parser be supported, will several parsers be supported, will alternative solutions be pursued or will nothing be done). But one thing you can expect. The decision will be done the current license in mind (non-commercial & free to use): http://creativecommons.org/licenses/by-nc-sa/3.0/de/deed.en And to continue. I am sure you have noticed that the ladder system & matchmaking has become a mess due to Blizzard implementing the MMR decay & not acting quickly when its effects became obvious. Due to the decay masses of different skilled players share similar MMR & even if the matchmaker is technically working fine (thought the league prioritization feature is unnecessary) the matchmaking results are often not fine (players with too wide skill difference are matched too often). Blizzard recently finally publicly admitted that there is a MMR decay feature and that they are evaluating the situation. Now as they have publicly acknowledged the issue, you can expect them to do something (potentially in start of next season as it is unlikely that they make changes in the middle of the season). They may even do so big changes that MMR calculations are not possible with current methods --> It may require too large effort to reverse engineer potential new system or even render third party MMR calculations impossible. Thus it is beneficial to wait and see what Blizzard will do, before spending potentially large amount of effort in development of the MMR tool at the moment.

It seems to think I win about 16 pts everytime i win. But where that circle is I had been leaving league constantly as a silver player but being put back in silver. When I lost that game at the very bottom (at presumably 166 MMR) it demoted me to bronze. Then I won the next game and it promoted me back to silver. So it would seem thats the boundary of bronze and silver. The game I won and got promoted the program declared I had an MMR of 280-something. But then later on down the line after winning 18 games or so more than i lost, it readjusted it by like a 100 pts. So something is wrong here, either its getting the boundary of bronze and silver wrong, or all my MMR values are not mid silver but very high silver. Image is taking forever to load so im giving up on that. Most of the 'leave leagues' were as expected regarding the placement league. You had some potential missing games in between thought. After the last 'leave league' you had 34 estimate games before the next 'good game'. It may just be that you have had lots of games that have changed your MMR more or less than the typical amount of 16. Here is how it adjusts the graph: On November 26 2013 19:05 korona wrote: Your MMR cannot be calculated reliably from all games. When you play a new 'good game' (a game from which the MMR can be calculated), it adjusts all preceding estimate games in the graph. For example if uppercase X and Y are 'good games', then the affected estimate games are shown in lowercase x & y (Note that 'Y' is the last 'good game' you have played):

Edit: I was able to get the same MMR state on both machines by copying the entire sc2gears (probably only needed MMR plugin folder) to my second machine. I guess I'll just do this every time I switch pcs until the original question is resolved. | ||
