Thanks for being helpful, but you do not understand my physical limitations. You seem to be presuming that I simply don't know what to do.

You don't get it. I can turn my hips back enough and my upper torso enough, but I cannot reverse the process as required. In the downswing, using an active pivot action, the hips need to move first while the shoulders are held back - that creates secondary axis tilt and then the right shoulder can secondarily come downplane (instead of roundhousing). I cannot move my right hip forward in a shift-rotation manner without my right shoulder immediately rotating forward - it is like there is a stiff metal rod going up my spine that attaches my pelvis to my shoulders. If my right pelvis moves 3-6" forward in the downswing then my right shoulder immediately moves 3-6" as well. Any attempt to square my hips at the start of the downswing- like Hogan in his video lesson - causes my right shoulder to move horizontally by about 6-8" in an OTT move.

No way! I have no problem moving my right hip back in the backswing and it certainly doesn't prevent my arms from moving correctly.
You also wrote-: "Also your arms are getting way lifted off of your chest . . . I mean if you want to get on the turned shoulder plane that's fine but you got some excessive lifting. --- You'll have to get your hands in and deeper. And your right elbow won't shoot up and off your body as bad."
I know all that because its is very simple to understand. However, I cannot get my left arm back along a shallow path that allows my hands to get in deeper below my right shoulder - because my left scapula doesn't move, which means that my left shoulder socket doesn't move around enough (despite a relatively good upper torso rotation). I have won many friendly bets from other golfers who have tried to prove me wrong. They have pushed with all their strength on my left shoulder to get it to move more around to the right during my backswing, and they cannot get my left shoulder socket to move around enough despite maximum push-pressure. I could be a millionaire by now if I placed huge money bets on this particular challenge.
You are correct that my right elbow shoots off like that because my hands don't get deep enough. However, I cannot avoid the right elbow positional problem because I simply cannot get my hands deep enough. The combination of high hands (near the neck) and a roundhousing right shoulder problem due to a lack of hula hula flexibility is why I cannot use the standard active pivot action. That's the whole point of my thread.
