That would be fine by me.
Then, we can speak of the OUTCOMES of the movement, such as extending up, or extending actively/passively, extending in a particular direction....
Here's a question:
Can we first agree that "Extending into the turn" is an OUTCOME?
If so, then what movements do you make to "extend into the turn"?
I would first say that "extending into the turn" is basically equivalent to "extending in the direction that your boot cuffs are pointing".
So going backwards from the extension, we'd have to change the direction of the boot-cuffs -- knees moving inside .
And before that, we'd have
-1) the feet tipping the skis to the new edges into the turn.
-2) the skis flat with the body travelling over.
-3) the outside leg flexing to release the CM.
The recentering/directional movement between-2 and -3 is left out, since the momentum of the release could have allowed the center of mass (CM) to proceed in exactly the right direction.
That *release* of the CM is the origin of "getting higher angles at turn apex". Get that right, and the dance with the mountain flows effortlessly.
