The problem is that pondering is part of the program. If you are trying to test which is best at playing chess then cripling all programs is not necessarily cripling them equally. What if some programs are better at predicting others moves and therefore gain an advantage by pondering more accurately. The same for learning/book learning. I'm getting suspicious that most of the improvements in new programs is just some "book-up" tricks against certain programs to gain quick Elo points. Disabling learning will allow these "tricks" to work continiously while book learning/learning will eventually nullify them. I don't know if you've seen my blitz database ratings but it seems the longer I play them the closer they get in ratings. My ratings also closely immitate the SSDF list by showing only a few points increase between the Chess Tigers and Shredders. Junior programs are showing up in the same fashion lately. I currently have Junior 9 trailing Junior 8 by 2 Elo points. I'm getting suspicious that top programs are hitting a "wall" and showing no real improvement in strength, only a change in the way they play. Just food for thought. Regards, Jim
