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?

Before year 2000, the SSDF rating for Excellence was 1757 and after year >2000 it is SSDF rated 1657. To be honest, I'm not sure what "Rule of Thumb" applies anymore, but I do think the SSDF is more accurate today then 10 years ago. I still find it ahem...dubious when I see Shredder 7, btw one of many great programmes I own, rated over 2800! That's Computer Chess...10 years from now those ratings will be deflated:o) Terry
