tdk6, Ron LeMaster did not just happen capture an overly rare position for Ted in that montage, and Ted does not ski Slalom making repeated unintentional mistakes,,, skiers that do that don't finish top 5 World Cup. Ted in the past has intentionally worked the tail more than most his competitors, and aft positions such as this at the end of the turn are the result. You asked in another forum if his pivot played a role in his fore/aft recovery. Very astute guided discovery question/observation. You bet, and it's why, even though in the launched image he appears momentarily grossly out of sorts, he is in fact in complete control of the situation, and actually gaining speed from his intentional catapult move.
As far as the application of this tactic to recreational skiing, I'm right with you, it's not a transition that the general public should strive for as a default transition. From a fore/aft balance aspect, better to emulate a Rocca transition.
On the other hand, Ted is displaying a balance/transition skill I strongly feel should be explored and developed, once at the appropriate point in the learning process. It's a skill that expands the parameters of performance options and the comfort zone. Once acquired, it's a skill that can come in quite handy on occasion. And outside the environment of rock hard steep icy race courses that require exact precision in execution, it's not as impossibly difficult skill to learn as some may think, once the proper prerequisite balance, edging and rotational skills have been developed. They actually can be great fun to do.
