I find this last paragraph somewhat disturbing as it seems to me to lack scientific consistency. Most games (most???) benefit from the PowerBook, and others used the ordinary. How precise can that possibly be? Sounds like a friend of mine who has the nasty habit of analyzing positions with conclusions that go like: "e5, f6, bishop takes rook and then this..." When I ask for precise moves he stops cold. Then there is the question of the RAM being used. Just about everyone in this forum knows by now that Fritz is a huge RAM consumer and benefits enormously from a generous amount of it. Fine, but I don't recall anyone going to such lengths to benefit other programs being tested. Did the other programs also benefit from at least 64 MB RAM? What about the aspect of the book learning? I assume the other programs with book learning had the same priviledges. The way the testing is presented it sounds awfully biased if you ask me. I am not questioning the possibility that Fritz 5 deserves the no.1 spot, but rather the procedures used to award it that spot. > >The margin of error for the rating of Fritz 5 is still >about 50 points, so large changes could occur when more >games are played.
