That is an interesting take but unfortunately it is not quite that simple to take a 2D view and compute the physics of rotational centers. From this perspective, you are focused on the movement (or lack of movement) of the trail shoulder in a global frame vs local frame. Because the entire body is moving in space, to compute upper torso rotational centers they need to be constrained to the local frame anatomy, typically something relatively immovable such as the sternum or perhaps a point near the center of the spine. I'll try to post another stickman from a different view.
Love you seabas22. A true og.
Another classic like Bird & Magic!!
Wow, very interesting! I’m leaving to go try it, right now. THANKS!
In this presentation it looks as if the both shoulders hit pass the exact same spot where the lead hip socket was positioned before the pull
