Agreed there can be that tendency and you can have a good amount of 2 without cocking the right wrist but there can be the tendency to cock the right wrist with excessive #2, what I do is lay the flat left wrist on the pads to double check it which is not perfectly anatomically flat slightly cupped as you mention in comparison to the left arm but in comparison to the plane it is flat, I think there is a reason that the angle between dianes left forearm and club shaft angle in ch. 6 demonstrating a fully cocked position was only around 70 degrees.

Diane?
 

Not to get off topic, but, who is Diane????

Is it the member of the B52's who doubles as the TGM book model?

As an aside, I hope that the next edition of the book comes out with clearer pictures....
