Mark,
Aside from formatting are you sure there is an issue. Could it be 100 %
of the time and 100% of the flops and since there is not room for all the
digits they end up sitting on top of each other?
Similarly could the flop rates be overlapped on top of each other? You
could try adding more digits in the print statement to make room for these
values.
