There is the concept of using a longer test (be it KM baselines, 20min, or even full 60min) AND doing the MAP test.
The relationship between the two as it changes with training and between individuals can really inform your training.
But yeah, ppl often don’t want to do those longer tests. It’s a shame because knowing both can tell you so much more than one or the other. And maybe even keep you out of internet debates 
. Win win
As a bonus, I no longer base high intensity off of FTP. No more “is it 120% or 130%” for a given interval set. I base it off of MAP.
Base work close to FTP off of FTP (longer protocol). Base VO2max etc work off of MAP.
As a side note, Ric offers group coaching, not just high end one-on-one.
