What is true is that 2300 FIDE does not equal 2400 USCF.


No Ken. That again is not information, its contradiction which /witholds/
information - which is sometimes denial, and from whatyouhave written so
far, indistinguishable from denial.


What did 2300+ elo equate with in USCF ratings in 1985? If you don't know,
its okay to shut up.


PI


Phil Innes, you have no idea to whom you are addressing.


Ken Sloan is THE AUTHORITY on this particular subject. He has done a
specific and detailed analysis comparing USCF Ratings to FIDE Ratings.
Nobody knows more about this subject than Ken Sloan.


And you, Mr. Innes, are an idiot.

YES! YES! YES!


Here is one of several charts comparing USCF Ratings to FIDE Ratings.

As you will see, a majority of the red crosses are below the green
diagonal line. This means that most players with both a USCF Rating
and a FIDE Rating have a higher FIDE Rating.

However, at the upper right corner of the chart mapping the ratings of
the top grandmasters, in those cases the USCF rating is higher.

This is the source of the myth that USCF Ratings are higher than FIDE
Ratings.

Also, the extreme cases, where there is a big difference between the
USCF Rating and the FIDE Rating, it is usually that the FIDE Rating is
much higher.

Here is one example: John Warlick of the US Virgin Islands has a USCF
Rating of 1584.

However, his last published FIDE Rating is 2205.

(Mike Nolan should note this on the USCF Ratings website.)
