Talk:Matchmaking/Seasonal Rankings

MMR Estimates: Read this first

 * This page is for discussing the MMR needed for each medal.
 * Keep in mind that Valve does not disclose the exact rankings, and likely does not use a single value to determine medal rank.
 * This means that any numbers put forward will only be an estimate.
 * Do not post here just to say that your MMR/medal is within a few hundred points of the figures given on the page. That is normal.
 * Do post here if you have reason to believe the entire table is inaccurate, based on multiple accounts (i.e. not just your own MMR)

Discussion
I collected data by adding random people from the dotabuff recent matches tab and by this reddit post: https://old.reddit.com/r/DotA2/comments/dg6br9/new_medal_mmr_survey_help_us_collect_data_on_the/ I was only able to get 8 data points but they range from Herald to Divine and are in such a straight line that I think it's enough to support my findings. Herald 5, 82%, 723 MMR Divine 2, 51%, 4923 MMR Guardian 2, 32%, 977 MMR Herald 4, 94%, 607 MMR Archon 3, 51%, 2698 MMR Legend 5, 13%, 3721 MMR Legend 2, 10%, 3260 MMR Archon 1, 88%, 2447 MMR

Finding a line of best fits suggests that the slope of the line is 156 MMR per medal with an intercept of -22 meaning the cutoff for herald 2 is 134 then add 156 mmr for each subsequent medal. This line of best fit has an R^2 value of 0.99988 and a mean squared error of 5.645. It is also independently supported by this post: https://old.reddit.com/r/DotA2/comments/dg36ke/badges_got_updated_4650_mmr_is_now_divine_i/ suggesting that divine cutoff is now 4650 where the line of best fit puts the divine cutoff at 4658. I've updated the page to reflect these findings, they're not perfect but it's a lot better than the page's current cutoffs. Aletheies (talk) 03:49, 11 October 2019 (UTC)


 * I already read that thread before making this page, your numbers seem low compared to some of the reports. 160 increments is the 'historical' distribution mentioned by Valve today, i think it's justified. We shouldn't take 4650 as Divine 1 based on one account. The numbers on this page are not supposed to be cutoffs, but approximations ~ (both higher and lower). Since Valve said the distribution will be unstable for the first few days, we'll wait and see. But i might have to change it back after everything stabilizes - Lemoncake  (talk) 05:14, 11 October 2019 (UTC)
