"are you the mysterious poster of yore posting as Guest ..."
No.
Observation stimulates curiosity.
Active re-direction/guidance of the skis beyond a pure carve is very real for all skiers - How this is 'managed' is one of the many challenges of skiing.
To me, those who deny its existence are naive. Conversely, it is interesting to have others share the physiological explanations of making it happen.
I do not need to defend. I enjoy watching skiers at all levels and see that a carving ski throughout an entire turn is the exception.
So, understanding how to manage this to complement one's entire skiing repertoire is important to all of us who enjoy alpine skiing.
Listening is an important skill in communication.
