Yes. If your Clubshaft angle at Impact is on the TSP, then it should be at Address. Your Hands may follow a Plane Shift during the Backstroke without the Primary Lever/Left Arm Wedge Aligned to the Elbow Plane. Then, at the Top, all is prepared by being already Aligned to the TSP for the Downstroke, Release, Impact and Follow-through. It's a simplified procedure.

I dont understand this very well. Does it mean that I must move hands first on elbow plane and then rise them, and still maintain shaft on TSP through all this movement?

I start my swing with rfta from address with shaft on elbow plane and hands in impact fix. Then I can feel (from elbow location when I start rising hands) the change of shaft plane (to steeper TSP plane). When I arrive to the top I already have shaft on TSP. That corresponds to single plane shift. I tried rise hands only without changing shaft plane and change shaft plane on the top, but not with success. I tried TSP plane for shaft from address to the top and back to impact, but with this setup I still cannot supply such power as in elbow to TSP shift.

Can I leave (for my full shots) setup with single plane shift with changed shaft plane or focus on zero shift and try build swing and add power after some time ?
