As time moves forward, so do the abilities of the players who play the setups. But for the oldest setups, dating back to setup 163, even a decent number of plays won't change the win percentages by too much. The points are calculated based on the statistical chance mafia/town has at winning a game, but some setups can turn from mafia-sided to town-sided or vice versa, thus making it more profitable to play a setup which is recently town-sided but statistically mafia-sided over all of time. So I ask that statistical percentages be based on the last N ranked games played, where N has an upper bound, an example being 500.
