What I want is to do it like all other do so people can compare, and ev. use it for the same tournament they allready find on the net to play with the result a little. In here we can discuss what is the best method, shouldn't it reflect if a player do it better or worse than expected? As it is now you can get a performance lower than your rating but still raise your rating points in a tournament. The same aply if you lose ratingpoints. For players with perfect (100%) score I like the USCF method with giving a performance of 400 point higher than highest rated opponent, or with 0% 400 points lower than the lowest rated opponent. But what to do with the rest to get rid of the strange looking performance. Use the 350 rule in performance calculating, whould that take care of it? Odd Gunnar
