Moves changed percent is it based on a number of games to the indicated ply depth? Big score changes?? What type of magnitude are we talking about here. I thank you so much for your response however I think I need to have an idea or atleast an approximation as to how long it takes rebel to reach the listed depths. I understand that it will vary at times depending on the position but a good educated guess won't hurt for the time being. Thanks, Les
