First of all I LOVE DIP TOO I was actually thinking of using it for games like Setters or Carcassonne or Ticket to Ride in our group of friends But anyway what about this idea suggested by a friend If player A wins against B and C then the Elo is calculated as if it were 2 games A beats B A beats C Is that any mathematically better or worse than the one you mention 08 18 Feb 27 2005 UTC
