includes the paragraph:
As an accredited Primary Movements Teaching System (TM) instructor, Clendenin uses Primary Movements as the focus for learning and improvement. "I use Primary Movements on the simulator because it works, not only inside but later on- hill as well. On the simulator you know immediately whether you are in balance or not. One cannot manipulate, rotate, twist, steer or force a turn. It shows up immediately. And when it does, it is easy to remedy."
That's why it reads similar.
I like his approach of the "4 movements" as it makes clearer that PMTS is not just about carving but includes a wide range of skiing effects. At it's core PMTS is about early release to the LTE and letting the weight shift create the release to initiate turns. The amont of engagement controls whether the turn has pure carved or drift components to it.
Interesting rewording of the same stuff with descriptions showing PMTS's broad application.
