I say the 10-18-C-1 backstroke is indistinguishable from 10-18-A. The amount of true wrist rotation which is suppose to distinguish between the two is the same. The only difference is that 10-18-C-1 happens more gradually and 10-18-A more suddenly in the beginning of the stroke.
One piece of advice for those trying to apply this info to their own swing. Use the wrist action you're most comfortable with to keep the Clubshaft On Plane. I see so many people who are doing well, and then they learn about Standard Wrist Action (Start Up Swivel) and they start going under plane and all sorts of compensations start creeping in.

Question: the subjects address position in the picture 10-6-B#1 shows the right wrist really uncocked. Is this required by the plane?
Regardless of Plane Angle, the Right Wrist is ideally held Level throughout the Stroke. The fact that the Wrist may appear Uncocked in 10-6-B #1 does not alter this Basic. It merely points to the fact that any photo in the book should be used as a check ONLY for the point under discussion and not those appearing incidentally (2-R).
And 10-6-B #1 refers only to the Turned Shoulder Plane Angle, not the Perpendicular alignment of the Right Wrist.
Study the Perpendicular Wrist Positions in 4-B-0/1/2/3. Especially study Photo 4-B-1. Level may be more "Uncocked" than you think!
Would it be fair to say that there is a greater range of motion from 'level' to 'fully cocked' than there is from 'level' to 'fully uncocked'? i.e. level is not 'halfway' between cocked and uncocked. Would apply to both right and left wrists.

Thanks for clarifying. You're correct about 4-B-1, it looks un-cocked but I understand the relationship to level wrt the forefinger.
One thing I could never quite get my head around was the concept of having a level left wrist at fix. If it is our goal to have impact as a pure hinge action - the further back of low point we go at fix surely the more wristcock there will be as the left arm and shoulder is above plane during the start impact interval until the left shoulder gets also to the inclined plane at followthrough when the power package is fully inline...
Also on a sidenote here with the rotated shoulder turn vs the onplane shoulder turn - The onplane shoulder turn is impossible accept initially in the downstroke as the axis tilts via hip slide - which spins the secondary lever assembly and right arm onplane like a flywheel.
Think about it - if the power package is fully inline at followthrough the left arm is onplane (or marginally parallel) by going to and in a straight line with the shaft (or more specifically longitudinal center of gravity) - if the left arm is onplane - the right shoulder/arm is onplane and lets say for simplicity sake the base of the neck is the center.... how can there be a position at the top to create this without moving the stationary point....
Let me do a demonstration to point this out - put a pen on a table (a plane) and press it in the middle to create a pivot point - now both ends of the pen represent a shoulder - now turn the pen notice that it does not leave the table - now think of a reverse motion from follow through back to the top of the backstroke - think about how the left shoulder could never actually leave the plane if the right never leaves the plane. This obviously doesn't happen in golfers strokes....
