When I try to translate and describe the feel I associate with proper acceleration I think of a rocking-like effect - not a swaying motion, more like the weight transferring down through the right foot into the ground and then rocking back to the left, planting the left foot, BEFORE the top of the backswing. An exaggerated analogy would be cracking a whip - you must start forward well before the whip completes it's backward progress or all power is lost.
Does that sound right to you, Daryl? It's almost like the sequence I'm describing must be standard procedure on full shots or loss of power (and fat shots) will result?

I agree with what you’re feeling.
The feet have a patterned and synchronized movement. Left Ball-Right Heel-Left Heel-Right Ball. Sit in a chair and tap your feet in this pattern over and over and faster and faster. Stand and do the same. The right shoulder accelerates when the left heel hits the ground (Classic Sit-Down) and is followed by pressure on the Right Foot Ball (not a push) to continue to turn the Hips to your left. Little kids do this foot dance while sitting down. Swing from the feet.
You'll look like this at impact if the Hips keep Turning and keep leading the shoulders. It's done with the feet.
Mr. Kelley pointed out the Four Periods of Acceleration in Chapter 8. Shoulder Acceleration (8-7, Start Down), Hand Acceleration (8-8, Downstroke), Clubhead Acceleration (8-9, Release) and Ball Acceleration (8-10, Impact).
But what is Acceleration? Acceleration is the speed of speed or the change in Velocity per unit time. Velocity, however, has a directional characteristic. If an object has a constant direction (moving in a straight line) but its speed is increasing we have Acceleration. If the object is moving in a circular motion with a constant speed the Velocity is changing because its direction is changing..and we have an Acceleration perpendicular to the motion (opposite to the force you would feel if you where in a car) or toward the center.
If both your speed and direction where changing, again we would have Acceleration.

My Friend,
Hmm? Yes, 4 stages of Acceleration but I didn’t want to talk about the Ball. I never mix Theory and Reality. It takes too much of the fun away.
Yes, Homer Kelley called stage 2: Hand Acceleration. I chose to call Stage 2 Arm Acceleration.
I wonder if HK would care too much.
My reasoning is:
As the Right Shoulder Accelerates, it carries the Arms, Hands, Clubshaft and Clubhead along with it. They are accelerating, but not away from the Right Shoulder. From the Shoulders point of view, they haven't move a bit.
During Arm Acceleration, the Hands and Clubhead are accelerating also, but not away from the Arms. From the Arms point of view, the Hands and Clubhead are getting a great ride but have yet to contibute any gas money.
During Clubhead acceleration, the Clubhead is moving away, but it is not moving away from the Right Hand. From the Right Hands perspective, the Clubhead is not moving away, it’s only traveling more distance.
So I concluded that we cannot call stage 2 Hand Acceleration because Stage 3 Clubhead cannot move away (Accelerate) from the Hands, but the Clubhead can move away (Accelerate) from the Arms and the Arms can move away (Accelerate) from the Right Shoulder. I’m being petty.
Acceleration “by the numbers”: 6-C-2-B and 6-F-1
6-C-2-B ANGULAR ACCELERATION The Clubhead “overtaking” speed is governed by the Law of Conservation of Angular Momentum whereby the increased Mass resulting from any extension of the Swing Radius decelerates the hands and unless they are supported by Power Package Thrust (6-B-1) or Throw Out Action (2-K), can result in great loss of Clubhead Speed. Rely on Clubhead Lag to meter out the necessary support for the Primary Lever Assembly. Strictly speaking, any increase in the product of Mass times Velocity is Acceleration whether or not the Speed is changed. But the formula for Kinetic Energy gives Velocity the greater value. And, actually, the acceptable tolerance in the Ball-to-Clubhead weight ratio is quite small.
6-F-1 “RIGHT” TIMING Maximum Force is delivered by maximum Thrust (muscular and/or centrifugal) near – but prior to – full extension.
Acceleration ceases when the speed it has produced equals that of the Thrust, and though the Thrust is still present and able to maintain Velocity, it loses the flexed, stressed Clubshaft (Hitters) and the wallop of the Centrifugal Force (Swingers).
The feet have a patterned and synchronized movement. Left Ball-Right Heel-Left Heel-Right Ball. Sit in a chair and tap your feet in this pattern over and over and faster and faster. Stand and do the same. The right shoulder accelerates when the left heel hits the ground (Classic Sit-Down) and is followed by pressure on the Right Foot Ball (not a push) to continue to turn the Hips to your left.

Hey D. You are on fire these days. Glad you're back on board the good ship LBG.
This reminds me of the McDonald drills with a dash of Yoda's knee sauce. The feet working as you describe and the knees breaking straight ahead, not side to side. As if its the hip turning that pulls the knees to the side as opposed to a sideways knee action. Is this right? I get my pivot in trouble when I toss my left knee to the right during the backswing. With it merely being pulled to the right, the move in the other direction is greatly simplified. Sort a like Knee/ legs version of hands to pivot vs pivot to hands.

Thanks for the compliment. I know that Yoda is waiting in the wings and letting me go on this until I really put my foot in my mouth, which I do more often than I like.
Your Knees move a little side to side because of foot roll which aids in Hip rotation. Sliding the knees laterally and causing the foot to roll gets things jerky and makes no restrictions in knee lateral direction or amount of motion. If you have a pure bend at the Hips, the knees breaking straight ahead and back (Bending and Straightening the Leg) Lowers and Raises (Slants) the Hips and moves them front to back. Lateral knee motion resulting from Foot Roll adds in a little circular motion to the Hips.
From the Ground up.
Recipe: Add one cup of Heel-Toe motion and a half cup of Foot Roll. The result will be that the Right Hip will move Back, Up and slightly rotate.
Performing the drill with or without foot roll to see the difference isn’t much, but enough.
Can you insert each of the above into their proper position/sequence in your three stage Acceleration description? Knowing where and when would really help me to understand how to synchronize the movement.

Ok, By the Book (its a TGM Coloring Book)
Left Heel Down - Shoulder Acceleration: Stage 1
Weight on the Right Toe - Arm Acceleration: Stage 2
Right Heel Lift Off - Clubhead Acceleration: Stage 3
