Thank you for your comments geoffda. I value your opinion.

re: alignment: I have been shop aligned, 1.5 degrees R, 2.0 deg left fat side out. The left knee rotates as it flexes. When fully flexed in the shop, it is on center. If I bend it further on the hill with weight on it, I can get the L ski to chatter as the ski moves in the arc past fall line - as if it's now very over-canted. I'm not convinced about the left needing 2 degrees if it's doing that.
The right knee had a partial meniscotomy several years ago, where the surgeon removed some material (arthritis he called it) so that it would ride smoother. That had the result of making the right knee less bowed.
When I am showing O-frame, I am deliberately doing it, so as to show that I can.

I have a thought about the divergence of the inside foot: It is exactly the movement that occurs at the foot when you double push on inline speed skates, but not as aggressively. If you've not seen the double push:

There is a hair of a double push in it, where the stance foot is placed down on the outside edge of the skate, then it proceeds towards the pushing leg after set down and steered back under the body into its main push. I suspect that the tipping movement to LTE has been strongly linked to steering my foot back under the body.
