“Shoulder rotation occuring at the same time as hip rotation simply can not and does not work.

I thank you for your kind assessment of my rotational swing model. I to think we are far more in agreement on energy transfer mechanics (especially the PLT phase) than our discussions may make it appear. I would also agree that much of our disagreements could be a matter of interruption. Your statement above ( >> agree, it is probably not even humanly possible to lock the two together during turning<<) is a case in point.
To me, “Shoulder rotation occurring at the same time as hip rotation”, does not mean they are “locked” together. How could they be, as Zig, points out, the shoulders are rotating at a higher rate than the hips. Below is a 2003 post I wrote regarding that topic.
One piece swing
Tom, I should be back at the office and able to post clips in a couple days. In the meantime, would you agree with my following statement? – “We all agree that rotating the hips is an important factor in the swing. However, I have always maintained that since the arms/wrists/hands/bat is linked at the shoulders rather than at the hips, the importance of hip rotation is its contribution to shoulder rotation." – Or, do you think that energy from hip rotation can be transferred to the bat without the shoulders moving (rotating or tilting)?
