Hi Bucket I'll give it a try...
A few years ago on a now defunct (Mike Austin) golf forum I wrote a post largely based on my reading of Nesbit's earlier research, I titled the "Golden Spiral Golf Swing". The idea is our hands should trace a spiral, and the origin of that spiral would be a point in space (perhaps on or in the golfer's body) but definitely not a body part (left shoulder etc).
The image below shows a golden spiral (fibonacci ratio 1.61
overlayed on the computer derived optimized scratch golfer swing. See how well the sprial fits (the second two phases of the swing)? In essence the fact that the radius (of the spiral is continuously decreasing helps prevent the early release or casting that costs golfers so much CHS. I suspect if Nesbit measures some of the top pros we will find their hands do trace a spiral (particulary the longer hitters ... people like Bubba and Camillio).
