I think I'm saying we're talking past each other.... the prior comment about geometry was using a simple model, that had nothing to do with pressure or the dynamics of a turn. It was simply this:Isn't that what I said too? How you interpreted it is what I got out of it too. What did I say differently?
When I said 'how wide you stand at the beginning of a turn' I meant horizontal separation. So what I meant to say is that there is no correlation between horizontal separation and vertical separation. That whole concept doesn't fly.
If that would be the case, then how could any PMTS skier achieve any sort of edge angle?

So to summarize:
What I am saying is that I believe that where your ski's are pointed at the beginning of a turn and the difference in pressure between outside and inside ski is far more relevant for vertical separation than how much horizontal separation there is at the beginning of a turn. Skiing 90/10 weight distribution vs. 60/40 will probably have more impact on vertical separation than horizontal stance width.
I don't believe @Rod9301 was getting at anything deeper... simple geometry says you take a stance of a certain width and tip it over, and you get a certain horizontal and vertical separation. That's the only reason to mention the starting stance - because the simple geometry view is that that determines the separations. So to paraphrase the original comment, "It's not possible for two skiers to have the same edge angle and different vertical separation, unless they also have different horizontal separation."
(@Rod9301 - my apologies if I'm mischaracterizing what you said. I think this is what you were getting at.)
Changes to this in practice are because this isn't a very accurate model of a dynamic turn, or of someone's legs. What you're describing is well beyond a simple geometrical model, although I may argue that the skis really aren't at exactly the same edge angle through the various phases described (I need to think about/digest that more).
