The problem is that these hubdreds of games are not games of the top programs and this is the reason that the rating are inflated. I do not think that top programs on pentium200MMX should have more than 2500 rating. The problem is that the difference between humans when one human beats another human 3:1 is bigger then the difference between programs if one program beats another program 3:1. Uri
