Scrappy is almost exactly 1/2 the speed of crafty. Same books and everything (except scrappy does not have all the 5 piece tablebases, but it does have most). Let it 'stabilize' for a week or two then start comparing them. That will give you an idea of what a factor of 2x does to the effective rating... > >>> >>>But seriously, there's no way I could give you a number without it being totally >>>random.
