Alright, Weighted Win factor finally Formula is:
(((Players_Town_Wins*(100 - Total_Town_Win_Procent))/2)+((Players_Mafia_Wins*(100-Total_Mafia_Win_Procent))/2)) * (Total_Number_of_Games / Players_Games_Played)
There ya go, maths for the win
OH, to to explain, first it is players number of victories as town times with how unlikely the town is to win, divided to half, then added half of the players mafia victories times how unlikely it is the mafia wins. Then those two numbers are added together and time it up with total number of games played and divide by number player partaked in, so the number of victories are seen in perspective with how many chances the player had to make those wins
