as I said, I am no expert about racing stivots...so I'm mostly asking questions and making observations... Though I know I have used something like this in my own free skiing numerous times to check my speed when I was hauling ass arc to arc.. When I have done it myself that way, I have felt that I have transferred my weight to the inside ski enough that I can then disengage the outside ski, fan it out a bit, scrub some speed, put it back online and then stand back on it again.
But here I have notated the montage with red and green lines for the left and right skiis. You can look at the knee orientation also to verify the direction the ski is pointing in each frame. its very obvious that his outside knee is getting turned in a lot more than the inside knee and femur which is holding much straighter to the line. The inside ski does pivot across a bit, but not nearly as much as the outside leg and ski. and the inside ski is much closer to the final resulting line around the gate, while the outside ski has to be reeled back in.
look at what he's doing with each knee through this whole process. As to which ski he is standing on with more weight, I have no idea, but clearly by frame #4 he would be outside dominant for sure if not before.... no arguments there Aman.
