Right, I wasn't speaking of vertical separation resulting from the inclination of the slope, though very astute of you to point out, as it does play a bit of a role. The vertical separation I was speaking of is that which results from tipping the legs, so as to tip the skis on edge.
Wish I had a drawing for this, suppose I should make one. In lieu of that, here's an attempt to explain it.
Take 2 pencils and stand them on end, side by side and straight up and down, eraser end down. Have them about an inch apart. Imagine they are your legs, and the erasers are your ski boots. Now tip them to the side, as though you were tipping your legs to put your skis on edge. Keep tipping until the pencils are touching each other. The distance from eraser to eraser is the vertical separation.
People have made a big deal out of this "vertical separation" term, because it describes a stance where there can be great distance between the feet, yet it can be described as a narrow stance because the legs are close together. It's the same amount of foot separation as when the pencils (legs) are straight up and down, but because in that instance the legs are further separated it's referred to as a wider stance.
This is why some people advocate having the feet move closer together as a skier goes through the transition, then separating the feet more again as the apex of the turn is approached. It allows the skier to maintain the same stance width (leg separation) at all times. If the feet hold the same amount of separation all the time the skier hits the apex of the turn with tight legs, a narrow stance, then goes through the transition with legs cowboy riding horse style, a wide stance.
Which takes us back to the heart of the question, how do we create that added separation as we go from transition to apex, then eliminate it again as we go from apex to the next transition?
