Pondering enabled can give theoretically a factor of 2 in performance when all guesses are hits (you have your and the opponent's time). In this theoretical extreme case pondering could make a difference of about 40 - 50 ELO points. In practice, there are less hits. So I arbitrarily guess that the difference could be 20 - 30 ELO points. Uli
