"The current study underscores that it is
impossible and dishonest to make comparisons between different
cyclists and to release individual values such as PO without the corresponding
range of random errors. This is an important limitation
of the current use of such Pest methods as exemplified in the mediareported
values for PO calculated from Tour de France ascents
and presented as accurate (without any mention of the confidence
interval). These values are produced to make comparisons between
individual cyclists and feed the debate about the ongoing prevalence
or decrease in doping in professional cycling. In our view, such
comparisons between individuals are inaccurate. The Pest method,
which takes into account a large number of observation points, could
be used to compare groups of cyclists (eg, over various long cycling
periods), but not when based on individual values."
