I think that there is a bigger statical error and I expect the difference to be more than 50 even for tiger in the next list The difference for Deep Fritz7 is 110 elo and the right gain is probably in the middle. (110+52)/2=81 is an estimate for the gain from the new hardware(52 is for tiger) It is possible to calculate better estimate by using more programs but I am too lazy to do it at this moment. Uri
