The SSDF list is simply grossly inflated. Programs are not playing at a 2700 level, if by 2700 the word "FIDE" comes to mind. The lack of human competition over the last 7-8 years has caused this, as machine-vs-machine ratings tend to get exaggerated. I can't count the number of times I have made small changes to crafty that would cause version N+1 to beat version N by a 60-40 margin, yet the rating remained _exactly_ the same on ICC. Most versions will beat the earlier versions by significant margins, yet the overall skill level gain (against humans) is lower than what is suggested by taking the win/lose/draw score and running it thru the Elo formula. As I have said before, the pools are totally different. The ratings are not comparable in any fashion until the two pools of players are merged and mingled enough that they can be treated equally.
