Just adding a few things to the above, just some things to consider specifically regarding scoring, specifically, ways to differentiate the quality of wins - my big gripe with the itc format is it doesn't account for this very well. W/L/D should be counted for, but should be weighted relative to a judgement of value. Adding this to whatever metric is determined for game points should denote the quality of the game based on the contribution of each player. In the aggregate over the course of the tournament, this should provide a realistic picture of each players' skill relative to others. The way the itc scoring works does little to differentiate anything but the top end, and even that may not have a clear distinction.
