@Bobby_Compton, Comment about your ‘eVO2max’; EVERY time you see VO2max as a parameter or measure of fitness on sites like Garmin, TrainingPeaks or intervals.icu, it is an ‘eVO2max’. The ONLY way to get true VO2max is in the lab, subject fitted with flowmeter and gas analysis equipment to measure metabolic response to a prescribed protocol such as an incremental or ramp test to the subjects maximum. All other estimates are just that, estimates. They should ALL indicate they are estimates. And to be even more pedantic about it in the Physiology literature there is the notion of VO2peak versus VO2max. VO2peak occurs when you don’t attain strict criteria that would qualify the test as being maximal, which can occur fairly often in patient testing as opposed to athletes.
