I hope someone can clarify a couple of things for me.
Question 1)
Mikaela Shiffrin uses the expression, "roll with ankles and knees," in her videos. Is it the same exact movement as the "tipping" in the PMTS or different? I feel the PMTS emphasizes on the lowest part of the leg, i.e., ankle, but not much on knee, maybe because the ankle movement will eventually move the knee movement. I don't know. Here's one of her videos:

Question 2)
An extension of the Q1 above: I now realize Harold emphasizes on the importance of bending and flexing of knees in this particular video. Perhaps, what Shiffrin calls "rolling" "knees" is what Harold is demonstrating in this video. He, in fact, says in this video, "Am I rolling my knees?" So, apparently "rolling knees" is part of PMTS, but is it the same thing as what Shiffrin says.

Question 3)
What does "Park and Ride" mean? Both Harald and Shiffrin use the expression. Having watched both Shiffrin's and Harold's videos, I think it basically means skiing without much control. But, what does exactly describe? Does it mean both skis are unweighted and not in solid contact with snow? Does it mean extending legs to push? Why is it called "Park and Ride"?
Thank you,
