I understand that it is not truth but you do not need to run 1000 games in order to check if the computer is 3-10% slower that is translated to a loss of 3-10 points. If you do a change in the evaluation function then you may need 1000 games in order to know if the program is better or worse but if you do a change that only change the speed of the program and not the evaluation or the search rules then the best way to test is not to play games. You can simply give the program to solve a test suite in order to check if it needs more or less time to do it. Uri
