I am not convinced that it is still linear. The only proof can be by games and not by the probability to change your mind or to find a new move because it is possible that the new move does not change the result. There is a point when it stop to be linear because you cannot improve forever and it is not clear where is this point. I know results of many games of pentium200 vs p90 at tournament time control but I do not know the same for faster hardware(p450 vs p200). Uri
