Well, those ratings that are re-calculated according to processors speed tend to
be a little odd, no doubt about it. I remember when Ed's Rebel 8 came out with a
similar idea, it was going plain bonkers when done on an AMD processor. As for
the no.1 ranking on the SSDF, it's true that Chessmaster topped the list once
just before they made the move to K6-2/450s as I recall. It was best of the
P90s.
