Hi Jim,
I've no racing background either (as you know from watching me ski!), but I'll take a whack at this pending input from any real PMTS experts who choose to follow and chew me up.
So as not to be biased, I watched your video repeatedly with the sound turned off. I have no idea what the commentator thinks beyond the suggestion of pivoting in the title slides.
The turn in question occurs at full speed from 0:36-38, and is repeated in slow motion from 0:49-52. What I see in that turn is NOT pivoting. Nor is there any early BTE engagement. Watch the slow motion segment and you'll see:
- release of the old turn by flexion
- weight remains on the old stance ski (it's not lifted, this is not a one-footed release/Phantom Move)
- the old stance foot, still weighted, is tipped rapidly toward its LTE
- the old free foot, still free, is lifted off the snow by the skier's COM moving down the hill
- the new edges are engaged INSIDE SKI FIRST, the outside ski is entirely off the snow during the High C
- the inside ski tipping/edging is not overly aggressive during the High C, the ski doesn't carve ... it BRUSHES
- as the skis approach the fall line, the outside leg is g-r-a-d-u-a-l-l-y extended to touch the snow, tip first, tipped toward its BTE... this engages both edges and starts the skis turning faster
- the outside ski only engages fully at the fall line, at which point he tips HARD and the skis finally carve and rocket around the gate
- the outside ski only takes a majority of the weight in the bottom 1/3 of the turn, just before he flexes that leg to release
SUMMARY: this is a Weighted Release/Von Grueningen turn with a Brushed Carve in the High C. Pure PMTS. No active pivoting whatsoever.
Hirscher chose this move because of the large lateral distance he had to cover between the two gates (accomplished by brushing the High C), followed by the very sharp turn needed to stay on line for the next gate (hard carve in the middle/bottom of the turn).
This is skiing at a stunningly high level, far beyond anything any of us will ever accomplish.
I expect I missed some points. Hope HH or bolter or another race coach chimes in.
