Sounds very scientific although unfortunately everything you have said here is still complete trash.

If the left wristcock takes place without a bent or arched condition, it moves on a plane that is aligned with the left arm. Since the left arm is not onplane and it is above plane therefore the left wristcock plane CANNOT EVER be aligned to the inclined plane.

There no other 'mystical' divergent vector alignments working here...just someone who cannot comprehend simple fact.

I agree with the post above. I was saying that although the left wrist cock with a flat left wrist is not cocking/uncocking in the plane of the inclined clubshaft plane - that doesn't mean that it creates an off plane motion of the clubshaft- which is what I thought Bulldog's post and Matthew's video were saying.

The left wrist cock and uncocking motion are just one of many "off clubshaft plane" motions that combine for the resultant on-plane motion of the clubshaft. Therefore, I don't think I said or certainly I never meant to say that the left wrist cock and uncocking motion with a flat left wrist was aligned with the inclined plane. That in fact was the point of my orginal post-that the flat left wrist with its cocking and uncocking motion is indeed NOT on the plane of the clubshaft- but contrary to what I thought bulldog and Matthew were saying "that therefore that would create an "off plane" clubshaft motion- I was saying that the left wrist can cock and uncock during a sequenced release on a plane that is not the clubshaft plane ("aligned with the left arm") and that will not create an off plane clubshaft motion (assuming clubhead lag etc.).
A simple non golf example is that you can throw a ball off a train in a direction perpendicular to the rail road track but since the train is moving down the track at a certain speed the resultant flight of the ball isn't perpendicular to the train track.

A separate topic and area of discussion on a similar issue- is the concept of the left wrist "moves on a plane that is aligned with the left arm". Since the wrist via the forearm and upper arm can rotate approximately 270 degrees- the plane of the left wrist cocking and uncocking has the ability to rotate 270 degrees (anatomcially speaking) so you have to ask yourself "What does aligned with the left arm mean or how does that help us define something important if the left wrist motion "always aligned with the left arm" whenever it is flat.
