who thinks they can hold 95% of a 20 minute effort for an additional 40 min.?
But the result will yield a higher 'FTP', so have at it.
Thanks for the info, btw
if one hour = approximation, then 20 min X .95 is another unknown variable added to the approximation. An approximation of an approximation.
Agree. All of these measures are just ways of estimating a somewhat theoretical quantity. However, the difficulty of giving a prolonged max effort is a key source of error and making the test more doable reduces it.
