I used adams fide rating and not adams uscf rating and I think performace should be the same. here is a link for fide calculator http://www.fide.com/ratings/calculator_rp.phtml It seems not to know to calculate performance because even 6 out of 6 will give adams performance of 2812. 6 out of 6 against players with average rating of 2000 give you performance of only 2075 for comparison 1 out of 6 against the same players with rating 2000 give you performance of 1727. It seems that fide performance calculator is biased against players who score more than 50% Uri
