Certainly! But, for example, 4-A is a Wrist Motion. Why add "Grip Motion?" Does this suggest how 4-A should be practiced?

There are three defined Left Wrist Actions for normal use. Single, Standard and Double. Left Wrist Action is in Zone 3.

Single:

1. Perpendicular Only
2. (Clubhead) Wristcock.
3. Wrist Motion Only.

Standard:

1. Perpendicular and Rotational
2. (Clubhead & Clubface) "Wristcock" plus "Turn and Roll".
3. Wrist Motion and Hand Motion.

Double:

1. Perpendicular, Rotational and Horizontal
2. (Clubhead, Clubface & Clubshaft) "Wristcock" plus "Turn and Roll" plus "Bend and Arch".
3. Wrist Motion and Hand Motion and Grip Motion.

One can choose Zone 3 to control one, two or all three. Clubface, Clubhead, Clubshaft.

Example:

1. Standard Wrist Action "Zero's" out (by using a Flat Left Wrist) Horizontal Motion (Clubshaft Control) by giving Clubshaft control to Zone 2 Left Arm Flying Wedge.
   
2. Hitters assign Clubhead Control to Zone 2. Swingers assign Clubhead Control to Zone 3.

These options are for creating a 2 dimensional Clubhead orbit follow a three dimensional path and make the Clubface Vertical for Impact. Only then, can Hinging control the Clubface Motion through the Impact Interval.
