Jim...I think your "ergo" is relative to those stepping stones fo skiing...those that allow the skier to ski efficiently and in control.

I think too there are many more stepping stones...those where atlethesisim, quick thinking, and adaptablity allow the skier to take those parallel skills and modify them to ski ungroomed and off piste conditions. Racers and extreme skiers are many stepping stones above we mere mortals but certainly you can see a variety of tools watching them ski in control.

Indeed, I believe a good parallel turn is a solid basis for advanced skiing.
