Ich habe ein ähnliches Phänomen beobachtet: Ich bin am Anfang in S4 nach Platin gesetzt worden, und werde seit dem auch überwiegend mit Platinleuten gemachted. MMR zeigt mich nun ebenfalls auf Goldlevel. Ich habe in letzter Zeit allerdings auch viele Games verloren, am Anfang des Graphen (wo ich gerade nach Platin eingestuft wurde) war ich ganz knapp über der Platinlinie. Ich denke daher das es kein Fehler ist. Bei dir scheint es, dass du sehr nah an Gold dran bist, sodass es schon sein kann, dass du nach Gold eingestuft wurdest. Außerdem musst du beachten, dass sobald du Gold bist, vorzugsweise mit anderen Goldspielern eines ähnlichen MMRs gemacht wirst. Dh. selbst wenn du dann viel verlierst, wirst du, obwohl dein MMR vielleicht wieder wieder Silber entspricht, eher mit anderen Goldspielern gematched, die ebenfalls viel verloren haben. | ||

Here (bronze-silver to master-gm): 280,300,280,250,250,400 As reference these were offsets for two last seasons (lower league offsets might be little too low): 200,185,180,185,200,290 On June 28 2013 05:25 trissi1996 wrote: I dont think the new offsets are correct i got promoted to gold 1 game ago and played mainly against gold opponents for the last 10 games or so. mmr stats shows nearly all of them in silver !!!PIC You had 4 silvers, 4 golds and 2 unknown (bnet profile problem or not ranked) opponents in your last 10 games. Good games were against silvers when you were in silver. It is possible that lower league offsets are off, but will not make changes to them for a while. The very little amount of data (I did not check the validity of the data) we have suggest the lower league offsets could be even larger than I set based on user graphs. And 'fix' in your situation would be decreasing the size. Will check lower league offsets again when more data is available. Keep on playing (you provide more data at the same time) | ||

There is something about this that I don't understand. According to these offset changes the current (and previous within parenthesis) league thresholds are as follows: 280 (200) silver 580 (385) gold 860 (565) platinum 1110 (750) diamond 1360 (950) masters 1760 (1240) gm If that's true, everyone previously in gold (385-565) should now have been demoted to silver (280-580). Everyone previously in platinum (565-750) should now be in silver or gold (280-860). Thats obviously not true. What am I missing? Also, if I look at my archived data my ending MMR previous season was 511. My starting MMR this season is 788. Why the jump? | ||

EDIT: I wrote a bunch of stuff, then second guessed myself. I'll let korona explain it. I'm not confident enough in my explanation to keep it here. | ||

It was a while since I looked at the MMR calculations too, but I thought that I understood them once. While I agree that league offsets obviously are involved in the calculations, MMR itself being dependent on them does not make sense. I'm pretty sure the real MMR (Blizzards) isn't. If you are right, this tool does not calculate MMR, but some sort of "pseudo MMR" which isn't comparable across seasons. | ||

If you are right, this tool does not calculate MMR, but some sort of "pseudo MMR" which isn't comparable across seasons. You can check the calculations & more info from Not_That:s thread: http://www.teamliquid.net/forum/viewmessage.php?topic_id=332391 And yes. This is a reverse engineered model that gives quite close approximations of your MMR. The Blizzard's model may be different like the info they have given suggests. In this model you calculate divisional MMRs (MMR for a certain league) and add the offsets to that and get your 'MMR' & your relative position in whole MMR range. Now indeed offsets & league sizes have increased compared to last 2 seasons. And relative MMRs compared to league borders have shifted. For example high diamond range players from last season became low diamond range players in beginning of this season. Please also note that these offsets are still small compared to the offsets used regarding WoL: WoL offsets: 585,345,345,255,380,(590) WoL prom offsets: 585,930,1275,1530,1910 | ||

Without delving into the algorithms (I really don't want to :-) it feels like all the necessary information is there to calculate an "offset invariant MMR". Not that many would find it useful. Just a few nerds. :-) | ||

MMR tool makes it so much fun to hunt for that promotion once you're getting close  Thanks! | ||

This mess thankfully does not affect MMR tool as I had accidentally set DB lock for Chinese server --> All games automatically set bad. Thus there is no wrong results caused by Blizzard locking and unlocking the Chinese ladder. I just released DB lock for China. Edit: This post discusses only Chinese server. No other servers are affected | ||
