(So book conclusions are much too soon) While I agree to the error bar statement I think it's clear a good book is worth additional rating points, how much anyones guess to a book maker it can be as much as 100 points. >For having included multiple versions of programs against a single one, >just search the forum, Dann Corbit e.g. explained it several times... >(Imagine e.g. what happens if Fruit doesn't like especially Fritz versions) Of course, but again in testing Fruit played against 20 different engines. True 4 were Fritz versions but again when it gets tested by the SSDF there also it may play only 6 or 7 different engines prior to it's rating being posted and there just playing a single engine it don't like, once can cause the same thing.
