Well of course giving one program more time gives the other one more ponder time. Lets assume that a program gets 50% ponder hits (a reasonable estimate, in games between computers it might even be higher), therefore 50% more time for the opponent translates to about 25% more thinking time on ponder hits to the program with the time disadvantage. So giving one program 50% more time is like giving the other one 25% time, so you only really increased the relative time advantage by 50 - 25 = 25%. Hence no surprise you didn't offset the 35% speed advantage. Perhaps try 70% time advantage next time? >Jim Walker
