Hi @LiquidFeet ! 
Will have to get back to you as your long post will require almost a line by line response. But as an example, you said
“your #1. Extend/lengthen/straighten both legs at the same time. Skier will be tall between turns standing on two long legs.”
We are not connecting on certain aspects of these ideas. Yes. Both legs extend. As in, both are longER than they were before the release. But it doesn’t necessarily mean the skier is “tall”. Only tallER. The magnitude of these moves will depend on many factors. But yes. This is the age-old up unweighting move that many of us learned years ago and that I would say is still the most common move for the average recreational skier. Also - absolutely no on “skier will be tall between turns”. In a typical extension turn, the legs lengthen to create the edge release then the skier generally sinks down ((flexes) as the turn develops. It’s easy to see because the head (also watch the pelvis) rises at initiation and then gets lower during the turn.
In a long leg/ short leg initiation, the new outside leg lengthens at the same time that the new inside leg shortens to effect the edge release. The head stays level throughout. It’s my understanding that Alberto Tomba was one of the first to popularize this method of turn initiation.
