I'll leave other folks to fight over definitions but what happens in
@Kneale Brownson 's video at :28 is what I do to initiate the carving (circular travel) process. I LIFT the outside edges of my feet; I don't roll onto the inside edges of my feet.
Now, if I am on a relatively flat surface at slow speed, I am relying totally on my weight to begin bending the edged ski and since weight is a gravitational term, I need to DIRECT that weight (Pressure) to the inside edge of the outside ski (PSIA fundamental #2). Because I am under the influence of Gravity for my upright balance, this requires angulation from the bottom up to build edge angles because I can't commit my COM to the inside less I cease applying fundamental #2 or worst case, fall over.
As speed increases, Centripetal force develops and gradually supplants gravity as the force for upright balance allowing the COM to move off its gravitational axis to the inside of the turn and align with the force rising up from the edged outside ski. This is where structural strength needs to be developed in the outside leg while the inside leg regulates its length in support of the edge building requirements.
My interest in this thread is simply that, when initiating a turn, we lift the outside edges of our feet vs rolling on to inside edges. In terms of movement patterns that develop from the two techniques (focuses), I believe the difference in ski performance is noticeable.
