you may be right... but then what are the hands supposed to feel in order that they might be able to control the degree of overlap?
There must be some sensation that allows for precise adjustment of overlap... just my guess that it had something to do with pp3 rotation...
Wait and see what answers others come up with.
My understanding is that the "overlap" in question has to do with the timing of the release of the accumulators. In other words, no overlap would be "release one... okay, now release two...", and total overlap would be one, two and three simultaneously, with most golf swings falling somewhere between these two extremes. Am I barking up the wrong tree, here???
