What you say sounds scientific, but I've played a lot more than 20 games against
people 500 points above me and have never come even close to winning (or drawing
for that matter) in standard time controls. Practically speaking, I think that
the ELO percentage estimates are based on mathematics and not on practical
results. It would be interesting to be able to search in the USCF database to
find out for sure.

I think what you say may be true for computers, but is probably not true for
humans.
