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.

No wonder you flunked out of college.

As usual, your observation is wrong. You cannot see
that the majority of the points are below the line, because
it isn't so. The green line is drawn in such a way that
roughly as many points are above as there are below.

The green line is not the 'diagonal' line. It is the graph
of the conversion function. The conversion adds points to
the FIDE rating to get a comparable USCF rating.
The correction is at most 50 points and is applied
to FIDE ratings above 2200.
