What an extraordinary post! That is one of the most hardcore theorycrafting I've seen around here, besides the SQ post. Very well done, sir. | ||

I have a question though cause I am in high diamond and I played with a master guy. His points was 245 and he had bonus pool 1. At that time bonus pool was 327. My opponend gained 11 points (but I lost 12). But from what I see 245 - 327 = -82. Is that normal? Can MMR take negative numbers, or I am missing something here? | ||

That means he has at the diamond mmr range and will be demoted soon, but that is a cool opportunity for you to understand where is your MMR at  | ||

If 327 is the Master number (or the number shown on the website), then the Diamond bonus pool would have been around 190. | ||

Would it be possible to make this work for teams or 2v2 at least (or does it work and i'm just doing something wrong?). Also it would be great if you could add multiple accounts to be "observed". Nice job so far Also great analysis! | ||

But all the code is focused on 1v1 and at the moment i just dont have the time for that, New version can handle mulit accounts and much more. | ||

Top of bronze is very very close to the top of silver. Same is true of silver and top of gold. I like how you have managed to infer so much. Very nice use of maths. But before you celebrate having it cracked i think the league overlap needs addressing before you can say you have figured out the actual mmr implementation and not created a model of it. You are close dont get me wrong but it is a simplification of the actual system. Unless league overlap does pop out of your system nicely. Will be really cool when sc2 gears manages to start capping data and you can test it properly though! That is pure awesomeness. This is almost like doing real science;) | ||

I'm not sure I follow. The actual league boundaries don't overlap at all. However, you don't automatically get promoted once you cross a boundary, either. Because leagues are subdivided into division tiers, the system requires confidence of which tier bests suits you in your new league. This combined with the moving average prerequisite means promotions can sometimes be delayed for a significant number of games. In terms of skill gap, it's true that the top of Bronze is relatively close to the top of Silver which is relatively close to the top of Gold which is relatively close to the top of Platinum, because Bronze itself covers such a wide range of skill. There's no actual overlap there, though. | ||

I want to see how close or far to masters I am. Also, while I am in high diamond, how offset works? Should I add 190 to the final result after "points - bonus pool"? I think it will be helpfull to add an example of a Diamond vs a Master to explain how does this work with results from different leagues and how the "Tier" part works. I know that I can use the plug in you made but I want to learn how it works. Thank you in advance. | ||

To calculate the MMR of Diamond from a match against Master: - Find Master adjusted points before the match. - Find Master adjusted points change from game. Insert the two into F function and get MMR value +- 16. Example from my last game against Diamond: My adjusted points before the match: 205 My adjusted points change for the match: 4 His MMR = F(205, 4) = 205 + (-256) +-16 = -51 +-16, so about -51. In the 43 matches I kept tracked of, I played 5 Diamond players with MMRs of -33, 37, 85, 38, -51. Personally I believe the line between Master and Diamond to lie somewhere around 0 MMR, but for the moment that's just an estimate. Here's my graph for last 43 matches. 5 of the missing bars are Diamond opponents, and the other 2 are matches where the opponent won and didn't tell me his adjusted points change and I was unable to determine it. ![[image loading]](http://s7.postimage.org/hfm9llplz/nt_games.jpg) | ||

For his adjusted points change, you can either ask him, or use this sc2gears plugin which does everything for you automatically. I know but it shows my mmr from 698 to -2 >< Shows my master opponents between 200 - 300, anything i can learn from that ? | ||

Before you can know the MMR of your opponents, you'll have to figure out your division tier. For example if your division tier is 300 points below Master league, you'll have to subtract 300 from the reported MMR of your opponents to know their MMR compared to Master offset MMR. Since you're playing Master opponents with MMR in the area of 200-300, your offset is likely close to that number taking into account that you probably meet opponents from the lower area of Master. How can you know your division tier offset is the million dollar question. | ||

To re-use the numbers that were provided before, 245 - 327 = -82 yes, meaning that Master player's adjusted points at the time of the game were -82. This is usually the case for players facing demotion. The offset from the bottom of Master to the top tier of Diamond is -150. Therefore, if you're in a top-tier Diamond division and played a +12/-12 point game with a -82-point Master opponent, you can expect your adjusted points (that is, your points - the current max Diamond bonus pool of the time, 190, + any remaining bonus pool you have) to be around -82 + 150 = 68. If you're in the second tier, you would expect your adjusted points to be around -82 + 150 + 63 = 131. Third tier, -82 + 150 + 63 + 63 = 194, and so on. | ||

Of course the "if your games are randomly sampled" is a big if. And it doesn't help you figure out which one you're in, but varying offsets will average out to some degree even in practice. | ||
