If you read and study PMTS books and videos and then pay attention to this whole Forum, is having someone else do your MA for you, even necessary? Every mistake in movement I see on the MA forum, is explained and demonstrated every where on the forum countless times. I understand that seeing errors in movement of a seasoned PMTS skier, might be a challenge, but from those that are not using TTS movements it's a giveaway.
All you have to see is a straightening or stiffening leg. An upper body lean or inclination, the lower shoulder at the end of an arc, ahead of the outside ski boot, and the big toe edge on edge at the same time as the other ski is flat. That just about covers it.
Don't tell anyone in TTS, oh yes, it's OK, they won't get it anyway.
