For a pure sequenced release a double wrist cock must be used.

I want to talk about the plane and the corresponding left arm alignments also. For every out of line alignment whether it be wristcock, wristbend, turning the hand towards the plane and the secondary hinge, it is actually impossible to overdo them on the backstroke provided they stay to the plane and its baseline which is ultimately under the control of the right forearm and pp3. If you were wishing to use a double wristcock in order to align the vertical wristcock motion to the plane - its adherance to the plane would mean that again you can not overdo it. Now when coming down the wrist can cock towards the line completely sequenced, and then since the wristroll and wristbend is two motions working co-ordinately, turning the hand back to vertical will automatically then bring it back to its 'flat' and vertical condition per impact fix...

That is how a 'pure swinging' sequenced release works....

I believe though that Homer knew this as it is hinted in 10-18-B double wristcock- "It is restricted to true centrifugal force Swings".

Ok so what about swinging with a strict left flying wedge. The lever assembly can still be accelerated via pp4 - the pivot to throw the wristcock which will automatically start the wristroll coordinately and still be by definition a swinger - using the rope handle technique.... The wristroll whilst totally co-ordinate works 'I believe' progressively 'faster' towards the end of the wrist uncock than at the beginning but yet it is still a full overlap of #2 and #3. I need to make up a graph at some point to prove this....

You know that you could bypass the complicated assessments of sequenced releases by becoming a Hitter. We've got it so easy. I'm a simpleton; therefore, I'm a hitter.

Like you, I am a huge fan of 1-L. I think if instructors truly took the time to immerse themselves in the study of the 21 basic concepts, they'd be better teachers. Though, there are some logical limitations in the drawing.

In three-dimensional Euclidean geometry, a sphere is the set of points in R3 which are at distance r from a fixed point of that space, where r is a positive real number called the radius of the sphere. The fixed point is called the center or centre, and is not part of the sphere itself.

Since humans have to hit the ball, we have a center working around a center. The left shoulder and it's distance away from our Stationary Post make the fixed point no longer fixed. Hence, a spherical shape cannot truly exist. But, as Homer said about golf, "demanding that golf instruction be kept simple does not make it simple - only incomplete and ineffective." This applies to three dimensional geometry as well.

We can both agree in the spherical geometry, if we see the left shoulder as the "fixed" center. But, we must also see the center's movement in three dimensional space. With this in mind, we can't even get an oblate spheroid, similar to the Earth's shape, because even this has a fixed center.

I appreciate your drive to understand more about this subject. Even more than that, I appreciate your drawings. They are priceless.
