I'm just wondering if Riot will ever make a mmr calculator cause all the sites out their that "try" to calculate your mmr are absolute ____. I mean op.gg gave me 975 mmr and then a few games later (all which I carried) and my mmr went to 650. Wtf?
When you hit the calculate button to update your MMR it rechecks the MMR of the people in your games who might have played more games. So their MMR is different from the last time you calculated. If everyone from your last game(games? not sure how many games it looks at) went on to lose a bunch of games then your MMR would be estimated lower.
