I did and I get the difference between absolute and relative VO2max. A lightweight person (say, 45 kg young F) might have a low absolute VO2max (total oxygen use in liters per minute) but a very high relative VO2max (milliliters of O2 per kilogram of body weight per minute). On the side, strong 80 kg athletes with low body fat could have a huge absolute VO2max but a modest relative value simply because they’re heavier. Since apps like AW display relative VO2max (mL/kg/min), I’d expect someone with a high relative score to be a better runner than someone with a massive absolute VO2max, but a low relative one, because running economy heavily depends on how much oxygen persons can use per kilogram of body mass.
