Heres a picture of Lynn I made from the film achieving a perfect Turned Shoulder Plane with Zero Shift.
Notice that the Plane Angle goes through the Sweet Spot, the #3 Pressure Point and the Tip of the Turned Right Shoulder at the Top. The #3 Pressure Point is ALWAYS on this Plane while the Right Shoulder Turns back to it on the Backstroke and then Turns Down it on the Downstroke.
