HaHaHa! Sure Paul, these ideas are very important.
Perhaps I should repeat that I am a PSIA pro. A very committed one. That doesn't mean I subscribe to the idea that the three outcomes I mentioned should be seen as final forms. The best manual PSIA ever produced was back in the sixties and it clearly states the whole reason they spun off from the other systems. They were committed to teaching functional movements instead of "final forms" like we saw from other schools. This idea wasn't exclusive to them though, the "new French way" also featured a stronger focus on functional movements. I suspect it was a reaction to the popular ski like Stein trend of the time. Interestingly enough Killy personified this shift in thinking away from final forms. So did Stenmark, Ghiradelli, Kjus, Meyer, and even Bode. These men redefined what we thought possible.
Fast forward to today and the ideas of alway parallel skis, shins, edge angles. This thread should clearly demonstrate that even though all four of these masters certainly know how to keep their skis / shins / edges parallel, in the specific situation captured in these photos none of those three objectives are occuring. Why, well that's exactly the point Rick is making. What we see are four very accomplished skiers breaking all three of these "rules" while performing at a level most of us will never truely understand. IMO it's a very valid point Rick has made, Versatility and Functional movements allow these men to transcend the dogmatic focus on final forms we see in the alway parallel theories.
Instead of trying to classify what we see as errors / recoveries / conscious technical moves, why not ask what we can learn from these masters? FYI, Chris Easton is a fellow I know who was one of the only people I've ever met who ace the RM examiners test (all 10's) and even twelve years ago he was talking about divergence and why it occurs. Barnes echoed this while in our school over at Keystone. Both saw the divergence Rick mentioned in his original post as a positive outcome of the inside half leading through a ski turn. I've already posted some of the "why it occurs but again I guess it comes down to the idea that there are no absolutes and no universally appropriate movement patterns. Especially in a race cource. Those men in the photos have a common thread of divergence occuring even though Ligety and Jansrud use more hip, Bode uses more knee, and Kostelic uses more inclination. That should debunk the myth of the universality of the alway parallel theory.
