That's way off.  Ken Sloan did a careful comparison a few years ago, and found
that at the 2500+ level, USCF was about 35 points higher IIRC.  Not over a
hundred as the above formula predicts.  IN fact, the conversion formula would
be a non-linear equation as the difference varies depending on the rating...
More at lower levels, less at the top.
