Just to give a feel for relative progress…absolute power improvement was not that much! Less than 5%, for sure. But time to exhaustion at that power is much, much better. I guess Seiler would probably nod quietly to himself.
but I will say that I did a workout during which I achieved 13 min to 40 min power numbers I’ve never achieved, ever, and AT concluded no adaptations needed. 
AT for the win!
