As Dr. Hyatt put it so clearly - "If >program A on hardware B beats program D on hardware E - does that say much about >A compared to B? This belies the principles of science - you have to have a >uniform platform for all participants to make any kind of judgement". You've quoted this ad nauseum, but failed to reply to several posts where I showed that your understanding of what A and B are in the SSDF is lacking. Recently someone else has questioned the correctness of your attribution of this quote to Bob, but it doesn't really matter to this discussion insofar as the comment doesn't apply when a correct interpretation of SSDF results is made. >That was quoted word for word from his posting on "Uneven Hardware dated >5/29/99.

Why do you insist on refuting this most logical explanation >of how to compare programs? > >By the way, my post was stated BEFORE I saw Dr. Hyatt's statement! > >Regards, >Mel> In addition to my comments above, if you want to compare software on equivalent hardware, then you can compare the ratings for the P200MMX machines, or the P90 machines, or the 486/66 machines, et cetera.
