Given the quality of the SC2 ranks data and the fact that blizz's data is absolute, I spy the chance of making inferences from them. Guaranteed you'll have error in any predictions (I'm guessing about 20% variance unaccounted for) but given we can know certainly when a person is promoted and their ranks / points when that happens... perhaps there is a way to associate the two. | ||

When ranking players, I like how the win ratio is incorporated into those two options, but it seems like (Points * Ratio) favors people who've played fewer games and been recently been climbing the ladder from lower levels of diamond. For example IdrA just climbed up from ~1800 to ~2600 in the last two weeks so he has a really high win ratio whereas IMmvp's been grinding at a much higher level over the last few months and he has a lower winrate as a result. Obviously the two accounts are on different regions and there are other factors that don't make it an ideal comparision, but I think this example still illustrates a need an option to account for the length of time the player has been playing at a high level when ranking players. Ideally, it would nice to see to see a formula to rank players that looks something like Points * Ratio * (sum(rank))^(-k) Where the sum would sum the rank (based on points at first) at X o'clock each day over the last Y days, and k is some positive real number that scales the weight of that term well. That way a player would benefit from being closer to the top of the ladder recently (where games are generally more difficult). After Y days, it could even be changed so that it's the sum of rank according to this formula itself, but I haven't thought that through. Doing that might have weird consequences. Anyways, no matter how it works, having that sum of ranks term would be really cool, but it might be prohibitively expensive to calculate. So I think something like Points^2 * Ratio * (Games Played) would work well and have a similar spirit to the formula above. It would be really awesome to see something like this implemented and see how that criteria would rank the players. | ||

I have a couple of suggestions to make it even better. 1) When I click "Que Refresh" it doesn't usually update my ranking in the 2-3 minutes it says it will. Sometimes it takes an hour. And, after it refreshes, the "Refresh Queued" message still shows. Glitch? 2) When you search for someone's name, usually there will be more than one person with the same name, or people that match your query. The way in which the list of searched people are sorted look kind of random, perhaps sort the list so that the best people are listed at the top and go down from there? For example, if I search "Ewic", I get like 20 results. Why am I listed at the bottom all the time when I'm the highest-point 1v1'er there? | ||

2) They won't be sorted, it would add something like 40%-60% load time (on queries that can already take 5 - 15 seconds sometimes). The alternative I mentioned above will solve that. | ||

We tried. It's not possible. There is simply too much hidden data. It would only be possible in certain contrived cases. For the overwhelming majority of players they get promoted fairly quickly (under 100 games played) such that their points lag behind their MMR significantly. This isn't even considering the division mojo done on the back end which further complicates things. | ||

Obviously performance depends on how often you flush the cache, but it still seems like a net win. Apologies if you already do this (I didn't read all 30 pages of this thread). | ||

Added profile finder, the point of the profile finder is purely for finding a single character, search is for everything else. For example, by entering: US, Shadowed, 1v1 team, Division name, DuGalle Eta I can find myself without knowing the profile link. Ideally you will use the division names because those are (relatively) static, but you can also use points, wins, losses or achievement points. When using a number, it will look in a band so 2500 points will find anyone named Shadowed with points >= 2400 and points <= 2600 on a 1v1 team. Division names searches are loose matches, so even if a division is named "Division DuGalle Eta" it will find it if you enter "DuGalle", "Eta", "DuGalle Eta" etc. Casing does not matter for division names. However it does matter for character names. For people who are using the API, I added an identical API that lets you search for characters to find their battle.net id rather than relying on character codes, see http://sc2ranks.com/api Small changes: "View Replays" is no longer shown unless the character has replays saved "Refresh queued" only goes by profile jobs, not achievement or profile jobs Total wins and losses are shown for map stats, for example http://sc2ranks.com/us/738095/Shadowed/maps/ | ||

Caching only helps if multiple people are going to be hitting the same page, the odds of the same person hitting the same search even 24 hours is very low. A page taking 10 seconds to load is already too slow, making it higher isn't acceptable. Hence why caching won't help since it doesn't help the initial load, pretty much every page is cached already. The profile finder I just added above solves the issue anyway. | ||

I'm assuming that it's gone permanently. I hope it is actually a bug, but I wouldn't count on it. On November 15 2010 16:25 Vulpes wrote: Asking the wrong guy on that.

It's really difficult to find people the way things are now. Use the profile finder, as long as you know a little bit of info like their division name or points, you can find their sc2ranks profile. | ||

Oh, I mean to contact them ingame to talk to them about various things, or for players to contact their opponents in tournaments. It's very frustrating. I feel it may be a privacy issue for Blizzard, but given how easy it is to block someone from communicating with you, and to set yourself as busy, etcetera, I don't see it being a very big problem. | ||
