[12 piece bucket]

Good post bucket...

The 'steady overtaking rate' of the swinger is certainly in agreement with the auto sweep release per 12-2, but digging deeper does this suggest that if done with 'right timing'(proper aiming point), a circle delivery would be best vs top arc straight line?

I'd have to so no . . . on that . . .

10-23-E CIRCLE Here, no straight Line Path is attempted. The Hands swing along on a continuation of the Top Arc formed beyond or above the Top-of-the-Line regardless of having reached a Top-of-the-Line position or not. So – from any Loading Point the Path to the ball, in this case is circular, and is used, normally, only with “No Axis Tilt” (2-H) and Arc of Approach Delivery Line (2-J-3). See 7-23.

Also keep in mind that the Circle Path is for less than full-power NON-PIVOT STROKES . . .

The Circle Path of the Hands is mandatory for all Non-Pivot Strokes (6-L-0) whether Hitting or Swinging (7-19). The “Axis Tilt” (2-H) allows Line Delivery Path but does not require it.

I'm reading betwixt the lines on the "steady overtaking rate" but I think he's refering to the Clubhead Travel associated with Horizontal Hinging?

Me and Mikey talked again the other day and he got me to thinkin' . . . I think this particular section of the book is a bit obscure, but I think it contains HUGE CHUNKS of what Mr. Kelley was all about . . .

Particularly with the necessary differences in Hand Speed, when Top Hand Speed as reached as a result of the differences in Loading (quick versus slow), what pressure points are loaded and the resulting inherent Hinging produced.

I don't have this section pat, but I think it's a puzzle piece that you gotta get. One thing I don't quite get is the part about Thrust equaling speed and then acceleration ceasing . . . how do you measure "thrust?"
