Pivot / Non-Pivot Stroke Delivery
 

Pivot / Non-Pivot Stroke Delivery may be found in 6-K-0 and 6-L-0.

How do we decide which one to use? Does it differ for Swinging and Hitting? Can you use a Pivot Stroke Delivery on the Backstroke, and a non-Pivot Stroke Delivery on the Downstroke, and vice versa?

Thanks :)

Oh come on guys! Spill your guts!

Zilla,

I'll take a stab to get things started. I'm by NO MEANS AN EXPERT . . .

But anyway, here's what the book says:


6-J-0 INTERPRETATION Power Package Delivery is presented so as to apply to the Circle Delivery Path as well as the Straight Line types but it must be interpreted to apply to the selected Stroke Pattern.

6-K-0 PIVOT STROKE DELIVERY In a “Pivot Stroke” the Power Package is held in a fixed relationship with the Body Turn and no independent Arm motion occurs until – or unless – the requirements of the selected Pivot are met. Then Arm Motion, independently or not, Continues Delivery per 10-19 until the selected Trigger occurs (10-20).

6-L-0 NON PIVOT STROKE DELIVERY In a “Non-Pivot Stroke” the Arm motion begins immediately and proceeds toward the Release Point as independently as possible of any incidental body motion. Monitor slow shots for “Clubhead Sag”, i.e. dropping Below Plane in either direction. See 2-N. However, for a Zero Pivot Sroke see 10-12-D.


I may be totally wrong here, but I would assume that Mr. K may be talking about less than full-power shots here?? Anyway . . . this is the section in 10-19 that I found relevant to this discussion:

The above characteristics apply to Strokes of any length. If you cannot handle both Short and Full Shots with the same Lag Loading procedure, you really do not understanding Hitting or Swinging. Master first the Short Shots – where you have time for careful Monitoring per 3-F-6. Two Procedures - presented in 6-B-1-D – will help reduce excessive Arm Motion in the search for the Feel of Lag Pressure. For Hitters – substituting Extensor Action for Acceleration in both directions. For Swingers – the “Bending Right Wrist” and/or “Extensor Action Takeaway” will – more or less, as desired – snap the Clubshaft into its In-Line condition (with Left Arm) with little or no Arm Motion except what results (intentionally) from Clubhead momentum

Yoda has advised that Mr. K was particularly keen on short shots in developing precise alignments and execution. There is another particularly useful procedure that is referenced above but further explained in 6-B-1-D:

This action of Extensor force can be substituded for Downstroke Acceleration of the Arms and Hands – in part or wholly – for “less than full Power” shots calling for the precision execution of a heavy, constant Hand Speed through Release and Impact. Lag Pressure then can be the artificial pressure of a tight right forefinger grip – which, actually, can serve the same function for Backstroke guidance (6-C-1).

Eddie Cox showed me this shot for short shots chips and short pitches. You basically PINCH the grip with your right thumb and forefinger. This will become the FALSE lag pressure. It is amazing how much THRUST you can employ using this FALSE pressure and how SOFT the shot comes off. I was amazed. After hitting the first few shots this way I figured based on the feel of impact I had blasted the ball across the green, but the ball comes off the club dead. Very effective and deadly weapon!

That's my take . . .

Power Package Delivery
 

Power Package Delivery refers to the Delivery of the Assembled and Loaded Power Package Down Plane to Release. Hence, it is a Downstroke concept, not a Backstroke concept.

The use of a Pivot Stroke automatically implies the use of a Pivot Delivery. Only where the Pivot Motion is incidental would it not be used to Deliver the Power Package. That is because both Hitters and Swingers properly utilize the Pivot to overcome the Clubhead Inertia during the Start Down. In other words, the Body Pulls the Arms and Club into the Downstroke.

However, once the Lag has been Loaded and the Right Shoulder has reached top speed, Muscular Thrust (Right Arm Drive-Out Action) takes over for Hitters and Centrifugal Force (Left Arm Throw-Out Action) takes over for Swingers. In other words, the Hitter uses the Body as a 'backstop' (the equal-and-opposite reaction) for their triceps-driven Right Arm. The Swinger, on the other hand, continues to use the rotary motion of the Pivot to Accelerate the Left Arm (via Momentum Transfer).

And yet the Hitter is Drive Loading and the Swinger is Drag Loading, even though both have this initial Pull by the Body (starting from the Feet -- gear train effect) at Startdown?

Going off a tangent here because I have many thoughts...get back on topic later :)

Yes, the initial start down for the Hitter and Swinger is the same. Once the hip slides and the right shoulder sets to become either a backboard or a gryo.

Hurry back I can't wait to hear what you are thinking.

Lag Loading In Pivot Strokes
 

Yes, both Hitter and Swinger use Pivot Lag (Hips lead Shoulders in the Downstroke) to Load the Power Package (via the On Plane Right Shoulder Turn Thrust against Pressure Point #4).

The essential difference between the two is what is being Loaded and how. The Hitter Loads the Right Triceps to Drive the Club through Impact, and he does so by using the Hands at the Top to resist the motion of the Backstroke Turn per 7-19-1. The Swinger Loads the Left Wrist to Drag the Club through Impact, and he does so by using the Shoulder Thrust to Snap the Club onto the Lag Pressure Point per 7-19-3.

"In other words, the Hitter uses the Body as a 'backstop' (the equal-and-opposite reaction) for their triceps-driven Right Arm."

Lynn,

Didn't get this at first....but it reminds me of an explaination Ted (I think) gave.

He compared the right shoulder's role (in Hitting) to jumping off the hood of a moving car vs. jumping off a stationary car.....he said you'll obviously go further if you jump off the moving car. Makes sense.

I hope I even got that analogy right....lol.

I thought it was a great analogy when I heard it....I feel the need to share.

Thanks Yoda, but...

Why is Pressure Point #4 not included in the Basic Hitting Pattern (12-1-0) since, like you have mentioned, Hitters also utilise Pivot Lag?

Three Accumulators...Not Four
 

The 12-1-0 Pattern is a Three-Accumulator Stroke. It is not for maximum Power.

My new conclusions
 

I see! I thought there is a bit more to using Accumulator #4 than merely utilising Pivot Lag. But no, so...

I have now come to a new conclusion that the 3-Barrel Hitting Pattern in 12-1-0 is inferior in terms of distance compared with the 3-Barrel Swinging Pattern in 12-2-0. Why? Geometrically, the effective Swing Radius is shortened by about four feet (or whatever the distance between your Shoulder and Feet). That is clearly a lot! Physics-wise, the Pivot Power supplying Momentum Transfer is lost. This places a lot of burden on Accumulator #1 which cannot fully compensate for all of the aforementioned factors.

Therefore, everything being roughly equal, if a competent Hitter wants to match the competitive and well-grooved 3-Barrel Swinger, he must use a 4-Barrel Stroke. Otherwise, he will start falling behind!

:)

(PS: I do not want this thread to have anything to do with the Right Arm Swing...looking at no one in particular ;) )

Wonder what Mr. K's input would be here? Tong are you talking 4 Barrel Stroke for the YOU at the "MASTER's level of execution?"

Or the less efficient like . . . well . . . 12 piece bucket?


10-4-D FOUR BARREL This high performance Four Accumulator Combination can produce many problems during its mastery by the player. But it can make the difference in top competition. Well controlled Double or Triple Barrel Combinations have little to fear from the Four Barrel Combination that is less than fully mastered.

I reckon it depends on who's pulling the trigger on the shotgun . . .

B

Yes, I'm saying at the "Master's Level of Execution", the 3-Barrel Swing will out-perform the 3-Barrel Hit distance-wise.

Note I didn't say anything about scoring performance.

Also Homer's comment about the "many problems during its mastery..." is directed more to the Swinger than the Hitter. In other words, the 4-Barrel Swing is not recommended at all, but the 4-Barrel Hit is recommended once you've mastered the 3-Barrel version.

Two thoughts/questions..

1. Isn't the above set up by the golfers alignment/position of the right forearm at the Top of the stroke? It as I think I understand it differentiates a hitter / swinger and how they can load?

2. Swinging vs Hitting I don't beleive it is accurate to say one is longer than the other. It may be in theory but in reality I beleive Mr. K. pointed out back in 1-D (Structure) which may be the most effective a golfer.

4-barrel swinging is a NO NO. I am in your camp!

Depends on the person, their strength and their flexibility, but I would agree for 'most' people that is a fair statement. Many factors involved though.
