mctrivia: I don't agree your second point. If I come to this site once a day, and play a move in all my games, then that will be rate of play, regardless of the time constraint of the games. I won't play faster in a tournament that has a 3 day move limit that I play in a tournament that has a 7 day move limit. I'd still be playing 1 move/game/day.
