If your builing a house, do you first worry about puting a roof over your head, or doing the landscaping?
Per Kelley, the SECRET, with knowledge of plane line tracing, is general direction control.
Zone 3 is finesse direction control.
With understanding, a person will realize that it is not logical to first focus on the clubface (obviously NOT talking about the simple act of initially aiming the clubface - certainly you'd want to concern yourself with this). It is likely the person will want to act in a logical fashion.
So zone 2 is the clubhead and zone 3 is the clubface. Even though PP3 is in zone 3 it only senses the clubhead, while the motion of the arms should control the clubhead ? This is cool, thanks Drew.
