I've always been unsure of a fair way to calculate opponent quality for 2on2s. The obvious answer of averaging player's quality just doesn't seem appropriate to me.

I'm personally against a monetary prize for winning jdc. If someone else wanted to give a monetary prize I suppose I wouldn't try to stop them but I feel like it might make the competition less friendly. If anything I'd support a prize that was more fun... say a jazz plushy doll.
