The implication of skiing into counter is that some combination of ski steering and lower body rotary is providing a steering action that turns the skis one way, while the upper body magically stays still. I think saying "skiing" into it, implies its the skis more than anything...the implication is let the skis do the work and just let counter somehow magically develop automatically as your skis turn under a magically stabilized upper body. Its implying that you don't have to worry about making counter-movements for sure, but its also implying that you don't have to make rotational twisting movements with your legs, the skis are doing it, they are "skiing" there. But that second factor is less important to my point...
Nothing is anchoring the upper body.... It does not develop counter automatically without counter-acting movements of the body in the opposite direction the skis are turning, even if the upper body is perfectly still relative to the fall line. That is especially true if the the skis are doing all the turning effort, but also still true if the lower legs are twisting that way too.
That is skiing INTO.
skiing OUT OF, two possible ways to interpret it, JASP still hasn't given me a clear definition of when its starts and ends.
A - SKIING OUT OF before the edge change, not possible. The body does all the unwinding work above the waist because the skis aren't steering back that way yet and no amount of twisting of your legs is going to make them turn that way either until they are flat. recentering can only happen before the fall line from unwinding your upper body. Could be tensional unwinding as JASP suggested, but I do not think there is normally enough tension there to recenter the upper body mass just by effortless spring action as he suggested. There is enough tension such that when your skis become flat they can pivot. But there is not enough stored force to recenter your upper body mass. You have to direct your upper body to do it, yes it can feel like natural unwinding but it still requires muscle activated rotational movements of the upper body to recenter, if that is your goal.
B - SKIING OUT OF after the edge change is not really skiing out of "counter"...its skiing out of rotated and skiing into early counter in the next turn.
So in terms of being able to say that people should ski into and out of counter, its not a sensical statement and it muddies up the try meaning and usefulness of early counter which is where the real emphasis on that word should be.
Option (A) is the only opportunity to ski out of counter so to speak, but its really not possible to ski out of it. You have to unwind yourself out of it.
option (B) does not qualify as skiing out of counter because at the start of the next turn with that rotational relationship you would not be countered any more. You would be over-rotated, or anticipated.
Further, I will state again that a more useful way to describe this particular move in skiing would be to say ski into anticipation. Because that is actually the desired outcome here. Anticipation is the thing being achieved, by skiing into it. Its still using counter-movements, but the point is that the end result is a particular useful skill in skiing, which is anticipation. Even though there is a counter relationship being developed there, because of the counter-movements being made.... The reason for doing it there is to establish anticipation. That is very different then the clear purpose of establishing counter before the apex.
Zenny you have stated that you unwind to square at the end of the turn..which means you are NOT trying to ski into anticipation, you are doing something completely different then typical PSIA. You are definitely losing the counter at the end of the turn, but I just think you are unwinding your upper body to do it, not "skiing out of it".
Other folks that are more PSIA in their desired approach, they are not trying to unwind their counter at the end of the turn, they are keeping it (in their mind they are skiing into it, but again I claim they have to have counter-movements to achieve it), but nonetheless, their entire purpose is so that at the edge change they will be anticipated. A fundamentally different task then early counter, the tradional and better use for the word.
None of those activities lends itself to using the slogans "ski into counter" or ski out of counter. Those slogans absolutely muddle up the meaning of purpose of what they are trying to do...and in the process, confuse the meaning of the word counter with regards to ski theory. They stole the word for the wrong purpose and in the process, created ignorant skiers that don't even know what early counter is. And on top of all of that....its not actually possible to ski into anything or ski out of anything....it requires counter-movements, even if an outside observer sees what looks like a quiet upper body.
