[O.B.Left]

The illustration on the left show you to turn the shoulders and then lift the arms to the top of the swing. The one on the right shows you to lift the arms which then turns the shoulders to the top.

The illustration on the right shows a conscious effort to trace the plane-line all the way to the top of the swing.

OK now I get your drawing, maybe. So you are taking Hands to Pivot to mean that the Hands proceed the Pivot in Startup? Is that right?

Why cant you turn the Shoulders and Trace at the same time? The Shoulders go one way the Hands and Arms go another?
