And at some point I realize I'm just sensing it as you say rather than thinking about it, at least until my next lesson when the instructor gives me something new to consider, or I find new uncomfortable terrain on the mountain.
To answer the question in your previous post as a segue to this one - it is exactly when exploring sensations (i.e. no longer concentrating on the basics of a given task) and when under-terrained that it helps to think about this sort of stuff.
One can think about it in terms of complete formalisms (in which case it helps to practice the brain off season) or one can use it as a guide to self-discover completely new sensations.
In that vein, and harking back to one of your preceding questions, I put it to you that having the CoM be completely stable with regards to a balance point during an entire turn phase is the essence of park-and-ride skiing.
