Not sure what %MHR would demonstrate.  Studies have shown that %MHR is 
about the same for both average athletes and fast athletes during 
competition.  %MRH is a measure of effort and I think everyone more or less 
tries hard in competition.  If stats were availabel for inline skating I 
think this would pervail. Agree that %VO2max differentiates. I think that 
heart rate would also differentiate the fast from the slow and suspect that 
the faster skaters would have higher heart rate.

It might be more useful to talk about %MHR -- percent
of max HR -- and even more useful to talk about %VO2max,
which is related statistically.

But even though there is some novelty in such numbers,
even those numbers are individualized.  If a person's
%MHR (or %VO2max) is higher or lower than some average,
it does not tell you much, especially without having
some correlating measure of performance
