interesting topic. i like the idea of skill ratings, but i tend to agree with inquiry that a tournament setting should be the method used. here's an idea (probably impossible to implement, even if it's a good one). skill should be based on result. why not either randomly or with forethought choose 10 hands an hour and designate those hands as 'rated' ones? the number 10 is arbitrary, it could be any number. randomly choosing them seems best. something like 'hands 1,3,5,7,9 for first the 30 minutes between the hours of 11 am and noon, hands 10, 12, etc for the second 30 minutes' as an example, by the end of the week i'll have played maybe 200 hands of bridge. of those hands, 20 will have been randomly chosen by the administrators (the same 20 that others are rated by). my scores on those 20 hands would be averaged, etc. i don't know, what do you think?
