Hi! There is no or very little inflation in the list. Everyone knows that todays better players play a lot with computers and therefore can find the "wholes" in there play (proved by you). I guess an experienced player earns 50-150 points vs the one that haven´t played computers. One of the only later results is from south-america where Hiarcs6, Rebel10 and CM6000 on P2-400 performed in average 2603 over 10 or 11 rounds. These matches with Rebel with very motivated ( prepared) players and double-increment time controls have nothing to do with the normal way of achieving an established elo (in tournaments). I think Rebel´s about 2500 under these circumstances is pretty fair. For the above most of the older programs haven´t moved much for years, but with todays knowledge on chess-program they are over-rated to. Of course we should adjust the level of the list as soon as we have some proper results. I think the list shows the difference between the programs in a rather good way. Anyone can adjust the list to what he/she thinks is the correct level. Regards Bertil SSDF
