I think that it is wrong to ignore it because the situation is not the same. suppose that you have 2 minutes to finish the game when the opponent played fast in previous moves and have 20 minutes to finish the game Suppose also that the opponent used 2 minutes for the last move. If you pondered the correct move you can use more than 2 minutes without losing on time(you count in that case also the time that you used in the opponent time otherwise you can never reply immediatly) and there may be cases when you want to do it(for example after a big fail low when you hope to find a better move). If you pondered wrong move then it is clear that you cannot use more than 2 minutes without losing on time. It means that the decision how much time to use from the time you started to search to the time that you play should be dependent on the question if you pondered the right move. Uri
