Different programs would break the experiment as >you start off with two variables, (a) program characteristics and (b) PB on/off. (a) is no disadvantage, it is advantage! It doesn't break, it makes it senseful! Read my other post. >using two programs is an ok idea, but this approach does highlight the >difference between PBon and PBoff pretty clearly. ?? Wasn't it you who once argued against playing a program vs the predecessor, so where is the difference now when playing the same program against itself?? I wouldn't even expect a 50% score both programs playing with the same settings.
