With your number 2 type transition, at some point between turns your skis will be flat, at that point, there is no centripetal force, and thus no added pressure other than your weight, extending you legs can only exert that weight, whilst when the ski is tipped centripetal force will exert a lot more.
I can't dispute any of that, I am not sure precisely the measurements of all those forces at the time. It might be interesting to rig up some sensors. Or not. My legs tell me there is a big difference in pressure between those two turns. What I can tell you is if I am somewhat late then not lot happens. If I get it right it feels like a shot-putter pushing themselves across the circle. You want to stay low as much as possible so it makes sense that as the ski flattens you 'hold fire' somewhat with the pushing for that brief microsecond. But if you're going to call that a 'float phase' then I'm not 'aving that .

The only point I am making is that you can't just create pressure spontaneously, you can move or maintain it (changing weight from one ski to another or fore and aft for example), but if you don't have the right amount of edge angle, nothing is going to happen when you 'press' on the ski.
I think I have agreed with that earlier. A couple of times .
What I would say is that there is a significantly different pressure profile for those two turns which is a result of my inputs. More than just a quick pulse.

The 60 degree slope thing is just to make you think about how you could press on a ski (without sufficient edge angle), whilst your body is accelerating at a huge rate.
We all have a speed limit at which we simply aren't athletic enough to keep up, just like running down a hill your legs are just pushing on thin air! Mine is quite low . Then it's all about speed control!
It would be interesting to rig up sensors, though an easy way to 'see' the pressure is the tracks on a race course, ruts deep at the gate, shallow everywhere else. I have only been hammering the edging thing because the thread was originally about grip, which to me is all edge angle, and rjs felt it was about pressure, which again, I felt was all about edge angle, but anyway, we seem to have run our course here.
Well, the person's real but it's just a made up name, see?

Just watched the stivot video, which is a great example of someone extending their legs and having no grip or pressure in the transition
