Subject: Re: How many points difference between FIDE and USCF rating?

I remember somebody doing this about 5 years ago, and posting the results in
rec.games.chess. If I recall correctly (please correct me if I am wrong), the
difference was only a little more than FIDE+50=UCSF.

While this seemed low, when you looked at the data it made sense. The first
people you think of in this comparison are the GMs with 2700 USCF ratings, and
2575 FIDE ratings. But there are a great many USCF 2225 NMs with FIDE 2290 type
ratings which counteract this. I personally know 2 local Masters whose FIDE
ratings are significantly higher than their USCF (i.e. FIDE2335/USCF2230, and
FIDE2180/USCF2090).

I think the assumption that FIDE ratings are over 1000 points lower than USCF on
the whole is a mistaken one.
