Another year of using WKO4 to crunch the numbers of cyclists power and other metrics has taught me that using short durations tests is a waste of time.
Majorly overestimate the FTP. Something Andy Coggan refers to as Vanity FTP.
Usual suspects are 95% of a 20min test or even worse a percentage of a shorter duration test.
Modelled FTP in WKO4 really highlights the folly of using just short term maximal efforts to determine threshold power, no matter what your definition of threshold is. A high FTP and a very short Time to Exhaustion (TTE).
This is well modelled in WKO4 for shorter durations as well. PMAX/FRC (Sprint Power), FRC (Track TT Power) and FRC/FTP (Pursuit Power).
