But, to defend Vincent and Arturo to some degree, I'm PRETTY SURE they were referring to a book that was specifically designed to be played against a single opponent. Somebody please correct me if I'm wrong. So, the only accurate way to test this (regardless of your argument that it doesn't need to be tested at all due to "common sense" -- which may be a fine argument but I'm not too sure it holds up scientifically :-) would be to create a book that is designed to exploit the weaknesses in Hiarcs' book, and then test with that. Then compare the results to using NO book, which, I believe, Vincent was arguing reflected the other end of the 700-point range. Will it show the possibility of a 700-point ELO gain? I very highly doubt it. But I do think it will result in a much bigger difference than the 3 points out of 100 that came from the first test. jm
