At higher level we sometimes want to build up tentions between lets say outside fist, outside hip and inside edge of outside ski but still allowing the needed rotation for proper stance and posture.
Are these assumptions correct?
Good rotation: allowing upper and lower body separation, angulation
Bad rotation: forcing hip rotation (-> outside) upper body rotation (into turn)
Yes, if I'm reading you accurately, your assumptions are basically correct. What you list as bad rotation is using gross rotation of the body to directly turn the skis. This is a low level skill.
Your good rotation examples are what we sometimes here call passive rotation: that which does not directly turn the skis, but allows for edge angles and balance states that cause the skis to turn on their own.
There is an active component to passive rotary and angulation though. The return to rotational neutral during a transition is often a very active and deliberate event that does not affect the efficient release or engagement of the old and new turn. We also can choose how early, and to what degree we want to enter into a state of counter for the new turn, again while keeping the quality of the new turn intact. And finally, we very much chose the form and amount of angulation we employ.
The rotation drills here carry the intention of helping people experience some movement patterns that produce rotational separation and angulation in a couple distinct ways. Falline poles is a very passive form of separation creation that causes what I call skiing into counter. The counter hops encourage a more active transitional rotational shift. Yet both would be considered passive in that neither should directly cause the skis to turn.
And do note, this is designed to be a quick jump start list of drills for skiers to do on their own. In a more in depth training sessions with students I would expand that list to include many more variations of rotary movement patterns, even the bad rotary you described. And I'd also explore the use of multiple forms of angulation for the same turn. It's all about developing awareness and expanding performance parameters.
Did I answer your question?
