I.e. one can assume a diff between 50 >and 100, possibly best 50 than 100. > I have looked at this casually , and there does seem to be a range of 50 -100 - .i.e., FIDE= USCF - (50 to 100). The players I looked at were in the higher range, For simplicity, 75 may work just as well since these are just estimates anyway. FIDE=USCF-75 or USCF=FIDE+75.
