Great analysis, Ray...Particularly the emphasis on tongue pressure at the 5:35 point...followed by his flexing through the transition at the 5:38 point to the next turn which gives the “appearance” of being in the back seat but, in fact, being in the perfect position to get the most out of tail propelling him into the next turn...pretty good clinic in that footage...
The explanations you gave show you see what is going on in skiing and is a cut above the vast majority of so-called ski instructors. 2:58 Try looking at what is going on from this perspective which describes what the person is physically doing rather than what it Looks Like he is doing. Throughout the turning phase when he is allowing the ski to make the turn to get to the point where the turn is complete. His right leg muscles are tense and hardened to resist the collapse of his legs due to the braking/deceleration action of the turn and centrifugal force. 3:01 When his ski is pointing in the direction, he wants it to go to set up for the next turn, he is relaxing the muscles in that leg which is actually allowing his upper body to stop moving to his left with the ski and keeps it going the way his skis Were going prior this point. If he had kept his leg muscles taunt, his upper body would have continued to the left and up the hill. Think of standing next to that gate while swinging a weight (Your upper body) on a rope over your head and then letting it go (relaxing your right leg muscles) at the point where his skis have completed the turn. Your upper body would head down the hill while your skis would continue through the turn on their uphill edges. 3:30 He doesn't bring his feet up so much as his right leg muscles are no longer supporting the weight of his upper body while the skis take his feet across the slope. His upper body is now heading down the slope while his skis continue across the slope. Because of his upper body movement down the hill and his skis crossing the hill, a new leg angle is created which rolls his skis over so the uphill ski can make the next turn. The focus in the skier's mind at the completion of the previous turn should be, "I want to go straight down the hill, get off my right arch and balance on my left arch." The first part locks the upper body on a down the hill direction, the rope release. The collapse of his right leg muscles allows the skis to squirt out from under him without affecting the path of his upper body down the hill. The step up onto the uphill arch, destroys the balance he had on his right foot which allows his upper body to fall and continue down the hill which creates the new leg angle which rolls the uphill foot over, so he is now on the inside edge of his ski. Like turning a light switch on and off. When you want the uphill ski to make a new turn, you turn off the downhill ski leg muscles and turn on your uphill ski leg muscles. To visualize this, imagine standing on the pedals of a bicycle. You create tension in your right leg muscles as you balance on that foot and relax the muscles in your left leg. The right pedal goes down. You create tension in your left leg muscles as you relax your right leg muscles. The left pedal goes down. Get off your left foot, get off your right foot. At the completion of a turn just think, "I want to go straight down the hill, get off my downhill arch and balance on my uphill arch." 4:00 Thinking about going down the hill puts your upper body weight over the tips of the turning skis. Getting off your downhill arch to balance on your uphill arch, destroys the balance you had on that downhill foot, and you fall down the hill which helps to create that new leg angle for your uphill leg to roll that ski over. Stand up now. Balance on the arch of your right foot as you slightly rotate your upper body to face to the right, down the hill. Now quickly get off your right arch (relax those muscles) and stand on your left arch (Tension in those muscles). Your upper body will fall to your right which creates the new leg angle that rolls your uphill foot over onto the arch. 6:22 K.I.S.S. He is on the bicycle. Point the front tire of your bike down the hill and pedal the bike. So, it isn't the "Thought" of bringing your feet up even though it Looks Like That. It's the collapse of your downhill foot's leg muscles with the strengthening of your uphill foot leg muscles combined with gravity which keeps you falling down the hill to create new leg angles.
Hi, Ray. That was a smokin hot run. Some of Ace's edge angles were sick, that one looked like 92 degrees or so. I liked your analysis, but am curious as to how you calculated the G force from the edge angle. I'm pretty sure that calculation would require a velocity component. If 2 skiers have the same edge angle, and one is going faster, the faster skier will feel more Gs, won't he?
No doubt he is forward but the measurements of ankle flexion are flawed by the fact his skis are not perpendicular to the camera but are partly directed toward the camera. Even Ace can't flex a boot to 29 degrees. Nor would he want to!

Great Run Analysis! ... like looking at Marcel Hirscher!! Kudos!
