Well said, just remember the famous Mark Twain quote: "removing all doubt"
Physics doesn't make movements or good skiing. Just look at Ron LeMaster, he talks physics all the time, he can't ski and he's very confused, but his Bulls--t baffles brains, just check out how often they quote him on Epic.
This is from a post I put up about 7 years ago. Skiing is about movements, learning what part of your body you need to move and do it in the right order, it's not physics. Physics and the relationship to skiing are academic, not practical. Ron Lemaster wants to make it about physics because he can write it down and draw diagrams that explain the environment and external force reactions. Even with that, he doesn't do it well. Why? Because he's justifying the PSIA methodology, it's like listening to Trump on the tax cut trickle-down economics, all bullshit. People who want to constantly relate skiing to physics, can't teach and can't ski.
