The Left Wrist is only Turned for the Swinger using Standard Wrist Action (10-18-A). Turned, as Yoda has confirmed, means that the Left Palm faces directly on the Inclined Plane. Any Cocking occurs independently of this Turned Left Wrist Condition, i.e. amount of Cocking does not affect how much the Left Wrist is Turned.

But if the left palm is on the plane, and the left shoulder is not, then neither is the left arm, hence there must be an angle between the palm and the arm - how can the left wrist be flat?

Or is it to do with the subtle anatomy of the hand (I must look like an idiot sitting here at my desk cocking my wrist up and down - my wife is always telling me to stop forming golf grips and the like when we're in public together!)

Thanks,
Chris
