Are you useing the correct formula? For hand: Average= 2713 Score=4/6=0.6666 From Fide site http://www.fide.com/official/handbook.asp?level=B0210 0.66=+117 0.67=+125 2713+117=2830 2713+125=2838 Twic have probably a calculator for this instead of looking up in the table. If you do a search in the archive you find some formula for this (1/2-1 year back). Odd Gunnar
