Fixing the formula for MMR update in team games #1

Closed alocate closed 3 years ago

alocate commented 4 years ago

Currently, each player in a team game plays an artificial solo vs an opponent of rating (sum of opponents' ratings - sum of allies' ratings) - this is equivalent to: current rating + (arithmetic mean of ratings for oppo team - arithmetic mean of ratings for own team)

It should be changed to: current rating + (geometric mean of ratings for oppo team - geometric mean of ratings for own team)

this will be consistent with the formula we use for matchmaking and team balancing
