The MatchMake API call allows the name of a player or character statistic to be specified to find the match that has the closest value to it but there's no documentation on how the match's statistics value is computed.
Is it based on the players connected to the match (average?) or does it need to be set manually (I found no API for that in the docs)?
Right now, stat-based matchmaking works like so:
The first player into a particular game server instance sets the server's statistic to the value of the player's. It's the use of StatisticName in the Matchmake or StartGame call that causes this to be set. When players search for a game session, the slot they are returned is for the session with a free slot which has a statistic value closest to the searching player.
