The idea is that I am _certain_ I am going to predict at least 50% of a good opponent's moves. But I don't have to wait until I do before I use that extra time. I can use it _before_ I save it, knowing I am going to save it. And if I don't, I am pretty sure I am going to win anyway because the opponent is going to have to be pretty weak. But I agree, 50% predictions returns 50% more time. Total = at least 1.5X, if you ignore the 'phasing' that occurs when your opponent predicts _your_ move.
