10-23 Power Package Delivery Paths
 

I have reviewed Brian's Driver Stroke -- I now have it on my own computer! --
and agree with you that his Hands may not be taking the Straight Line
Path of 10-23-A. Instead, it may be the Angled Path of 10-23-B, and I
have edited the original post to reflect that conclusion. If it is the Angled
Path -- I would need a down-the-line view to tell for sure -- it would be
compatible with the slight Plane Shift in the Backstroke noted in my original
analysis and would return him to Impact in perfect alignment.

I also agree that the Iron Stroke clip appears to use the Straight Line
Path.

Regarding your question about improving by sustaining the length of the Line
Paths:

It doesn't take much to satisfy the Straight Line requirements of the Line
Paths; a little will do. Then, the Release Trigger (7-20) will
determine how far down the Path you continue to go. This is the 'Pulley Wheel
Encounter' of the Endless Belt Effect (2-K #6).

An early Release Point -- Sweep Release -- means an earlier end to the
Straight Line Delivery Path -- but not the Thrust! -- towards the Aiming
Point (6-E-2) and a 'larger Pulley Wheel.' A later Release Point -- Snap Release
-- means a longer Straight Line Delivery Path and a 'smaller Pulley Wheel.'

The larger the Pulley Wheel, the lower the Clubhead Speed for a
given Belt Speed (Hand Speed). Therefore, to achieve a given Clubhead Speed,
Sweep Releases require a higher Hand Speed than Snap Releases.


In the right Hands -- pun intended! -- both can be equally effective.
