I give it bigger probability relative to the opposite case. Practically the standard error is too high to be sure about it and it is also possible that program B will be again weaker at 2000 MHz so I cannot be sure about it. > >Or is it all just a big crap shoot when you are talking about the top ten >programs?

Saying that A is better than B in chess does not mean that there is no position that B is better than A. Uri
