Most POV cameras have a very wide angle of view, but your hands are not always visible. Is it possible you're bringing your hands up because they've dropped back? If so, the hand movement and dropping your hands back certainly will interfere with your balance. Can you see your hands out of the corners of your goggles without looking down at them, or can you see them only when you bring them up?
You might try keeping your hands far enough forward so that you can achieve a pole touch with a flick of the wrist, rather than having to move your hands and forearms so much. Being able to see your hands most of the time might help, too. Lightly dragging the pole tips might also help, as has been suggested elsewhere. Be sure to drag them both to feel centered and avoid leaning excessively to one side or the other.
Perspective might be distorted because of the POV camera, but it also looks as if your "stab" is almost straight down below your hand location, rather than being a reach toward the next turn. Is this impression correct, or is it an artifact of the available perspective? If you are really driving the pole straight down, your hand will tend to drop back.
Point being: You want to get as much proprioceptive feedback as you need, with minimal arm waving or windmilling. Keeping your arms in a position ready to receive a hug might allow you to get the necessary feedback with less actual arm movement.
A PSIA Examiner friend of mine has been known to advocate the occasional double pole plant, particularly in gnarly bumps, to help with re-centering.
What do you do in very soft snow, when the stab or plant doesn't necessarily meet with the desired resistance?
You might also see if you can talk to Beth Fox of the National Sports Center for the Disabled in Winter Park. She could have some insight on how to manage with your SPD. She's pretty high up the food chain there, so she could be difficult to reach. Keep trying.
I could be dropping my hands back. When I'm not actively in the process of turning, I tend to drag poles, which would put my hands lower.
I think I will try skiing with the hands up. If I can see them, I have more of a chance of not mirroring or stuff like that.
Yes, in many cases, my stab is brought further in than normal- maybe only a few inches in front of the binding. I know to extend out and try, but as the video shows, the timing of my pole plants is just all over the place and pretty terrible. Part of the windmilling problem may be me trying to get the shoulder back forward after they have been dropped back while I am shoving off.
Maximizing proprioceptive feedback is the name of the game. I don't get very much without really working at it. As I kid, I broke all of the toes on my feet except the largest, some multiple times, from walking into doorframes while attempting to walk through doors. Thankfully I've gotten better at that, but in general I am just clumsy as hell.
I get that the occasional double plant is a tool in the toolbox, but what I am doing is just not that. I am sure I will also need to double plant more than most throughout my skiing life, but I think it has turned into a crutch that I use whether I really need to in the moment or not.
Regarding what happens if I stab and don't get a platform to push off- if I misjudge how much I have to work with in pushing off of the snow, what I will try to do is bring the skis around as fast as possible in the direction I am falling sideways to hopefully get them under me. If I don't I fall. I bought powder baskets to maximize how much I have.
I may actually have some non-pov video from the scant handful of days that my wife had the camera and we skied off-piste. I'll check to see what I can find.
Finally, because it seems like this thread has turned into a little bit of AMA about my disability status and it feels weird to talk about one aspect of it without mentioning the bigger picture, I feel I should just go ahead and mention that I am an autistic, and like the overwhelming majority of those with autism (somewhere around 75-90%), significant difficulties in sensory processing come with the package. Its not directly related to the skiing issues, but I think this thread would be helpful for somebody trying to figure out why the person with autism they are teaching to ski is wildly flailing their arms, and unless I say autism in the thread, it won't get found. :)
