Ron LeMaster's MA of Lindsay Vonn includes the following:
By Ron's definition/use of the term, Knee angulation: drive the outside knee inward to edge the ski.
Independent leg action resulting in the lower legs being something other than parallel.
Vonn carves predominantly with the outside ski, actively adjusting its edge with knee angulation throughout the turn and uses her inside ski as more of a balance and pressure adjuster than as a carving tool.
Having a lot of knee angulation and tip pressure going into the fall line serves her well. But if she were to not make the right adjustments when she gets into the last third of the turn, she would encounter a problem common to lesser skiers who get to far forward on the ski going into the bottom of the turn, causing it to oversteer and the tail to flair. The trick is to decouple the dorsiflexion of the ankle from the inward rotation of the leg. She keeps her outside knee in while sliding her foot forward. Where the natural tendency is to let the outside leg turn outward as the foot slides forward and thus reducing knee angulation, the best skiers can keep the outside leg rotated inward while sliding the foot forward. In other words they control the skis edge and fore aft pressure independently.
Any comments?
So much of this is directly opposed to what I see and believe to be right, some things may never change.
Knee drive
pushing foot forward
inside leg balance focus
