Yeah, cool opportunity and I’m sure very effective marketing for zwift and whatever were the certified platforms / power meters for use. I assume that he’ll have to do a ‘weigh in’ to confirm the W/kg !That's it pretty much.
Problem is it doesn't take into account racecraft and bike handling skills.
It's a measure of w/Kg and VO2 Max which are predictors only of ability.
Good luck to him though with the opportunity...
