If SSDF has reduced their list down by 100 pts. (as they did in year 2000 sometime) then should we not add 300 pts. to continue to be on par with USCF? Or is the add 200 pts. still a valid rule of thumb? If so, why the reduction by 100 rating points by SSDF? What changed? Did SSDF decide from experience that the ratings were inflated by about 100 pts. as compared to ELO or Swedish ratings for human chess players? Kerry p.s. Before year 2000, the SSDF rating for Excellence was 1757 and after year 2000 it is SSDF rated 1657.
