You can see that at the time of promotion, there are people on Contender with MMR more than enough to be promoted, who meet the activity requirement (10 games in 3 weeks) that don't get promoted into GM, but people below them do. | ||

The outliers from games with unranked opponents also show an MMR gain of 46 (for 1101 and 835 rating difference games), which must be the maximum (the minimum being 0). There's probably a lot more to be gleaned from this dataset, such as learning the relative trends of system confidence (you can see in the second chart that the rating difference gradually closes). This is pretty fun and cool stuff. Thanks again for sharing! From what I can tell it looks like (approximately): Change in MMR = +/- 22 + 0.025x(opponent's MMR less your MMR)) obviously '+' if you win and '-' if you lose. The data doesn't fit perfectly. So if you play someone with 100 MMR more than you and you win you should get 22 + 0.025*100 = 24.5 increase in your MMR (maybe rounded up to 25). Your opponent's MMR falls by -22+0.025x-100=-24.5. Data fits much better the more games that are played. Where there are large outliers it's in the first half of the dataset mostly. Interesting that it takes over 140 games to get to 5000 MMR which is probably below this person's true level. And it takes 80 games to get to 4000 MMR (my level) which is way below this person's level. | ||

The formula itself would have to be exponential. Something like 46 * (1 / (1 + (10^(-(rating_diff)/800)))) where going from rating_diff 100 to 200 has a bigger impact than going from 600 to 700. The 140 games to 5k MMR (this account reached Grandmaster after the final game, if you were wondering) was only because it was a borrowed account that started from 2k MMR, below the Bronze floor. Placement matches swing your MMR pretty widely, probably 100-150 per match, which never puts you that far away from either end of the spectrum if you're starting a new account, since the seed MMR is around 3200-3300. | ||

Under TrueSkill, your change in MMR depends on your MMR uncertainty as well as the difference between the 2 players MMRs. And the relationship between the change in MMR and the difference between the 2 players MMRs is nonlinear, but approximately linear as long as the winner does not have significantly larger MMR than the loser. | ||

For example, Plat 3 is now 3520-3626. Previously, it was 3480-3600: http://wiki.teamliquid.net/starcraft2/Battle.net_Leagues#League_MMR_Ranges | ||

In order to fix them, rather than rolling back to the old values, they just recalculated. It's going to make that page a little inaccurate since it means replacing filled cells, which isn't going to get quite as much crowdsourcing support as if those cells were empty at the start of the season. | ||

It'll encourage you more not to "grind" many games, but to play only 3 per day, until skill is dwindeling. | ||

They said they were increasing the size of masters.. doubling it from 2 to 4% But myself and several others I know who were low masters are now tier 1 diamonds.. I'm personally a long way from masters where as prior to the ladder reset I was masters the previous 5 or 6 seasons I'm not upset or anything.. just wondering if it's actually 4% now or if it's the 2% claim that was inaccurate | ||

Master 1 changed to 6500-6611, Master 3 was 6280-6390, Diamond 2 was 5746-5973 (NA) 5760-5933 (EU). Then apparently it was erroneously pushed to the live servers. This happened on Friday afternoon and lasted for about 2-3 hours. On August 03 2016 01:40 Ignorant prodigy wrote: Hey Excalibur, do you have current ranges of the leagues based on population?

What that means is that the 96th percentile of users last season had an MMR of 4640 or higher, so that's the new boundary for Master 3. One thing they mentioned in some Q&As is that they were messing with the percentiles for Master league during HotS/LotV without revealing their new target. They tried 6%, they tried 8%, but we continued to operate on the assumption that it was 2% the entire time because we didn't have any updated information and the community's existing tracking methods weren't aligned with what they use internally, so we didn't know how close we were. We don't know what the target was before the ladder revamp, but we know what it is now. | ||
