the requirement was to exceed 2500 USCF.  they hit right at 2600 USCF.  I
didn't acknowledge anything different.  And _nothing_ I know of says that
USCF = FIDE+100.  In fact, Ken Sloan (in the CIS department) did a detailed
study and found that above 2400 or so the ratings are far closer than that

He published that in r.g.c.c about 2 years ago.  It hasn't changed that I
know of.

This is not the first time you make an error in a statement, then refer to
the original error as fact.  DT had a rating of about 2600 USCF over 25
consecutive games.  You can find the exact details in the JICCA announcement
where they were awarded the prize.

You really have this 'envy' thing going, don't you?
