I love that super heavy inertia feeling.

I push with pp#1. But that's hardly a secret by now

Unfortunately I am not able to pruduce that kind of action on every stroke. Far from it.

Thanks for this discussion. I am taking it in and ruminating.
Some time ago I was trying to really stress pp#1 and usually liked the feel as well as the fact I was maintaining my flying wedges and some lag for the first time in my life. Sometimes shots would be a bit to the right and in the beginning that didn't matter since I was striking it so well, but it then became a concern.
Focusing a little more on #3 straightened things out quite a bit and I have been actually hitting more targets, greens especially, than ever before.
Then I noticed my left hand was getting a little too weak and my grip alignments were a little off. If it isn't one thing, its another. I am not complaining though, because now I actually have a bit of a clue what to do to make a correction instead of a compensation.
Geez, I love this TGM stuff.

I believe Mr Hogan is describing what we would term Indirect Drive, Inertia , Lag Pressure at the index finger, on the aft of the shaft , associated with Radial Acceleration.

I can't get that term "Indirect Drive" in my head. Would you help explain the differences between "Direct" and "Indirect Drive" in the Sections below?

Quote:
10-11-0-1 PRESSURE POINT #1 (above) is active Power Package “direct drive” (7-11) of Accumulator #1 for actuating the Primary Lever Assembly (6-2-A) for Hitting (10-19-A) as well as Extensor Action (6-B-1-D). It is Loaded (7-22) per 6-B-1-0 and 7-19-1. It is only a passive “direct drive” with any true Swing procedure – Right Arm (7-19) or Left (6-B-3-0) – except per 2-M-3.

10-11-0-2 PRESSURE POINT #2 (above) actuates the Secondary Lever Assembly (6-B-2), normally, only as “Passive Clubhead Lag” (6-C-2-A). It is Loaded (7-22) per 6-B-2 and 7-19-3 and is a Swinger’s Rope Handle application (2-K, 2-M-3).

10-11-0-3 PRESSURE POINT #3 (above) can be either active or passive (6-C-2-A) Accumulator #1 indirect drive (7-11) of the Secondary Lever Assembly (6-A-3) (2-K). That is, actively as Accumulator #2 Axe Handle application for Hitting (10-3-K, 10-19-A) but passively as Accumulator #3 (6-B-3-0, 10-19-C) or with a Right Arm Swing (7-19). Lag Loading (10-19) and Delivery Line (2-J-3) requirements. It is Loaded (10-22) per 7-19 as required by Component 19 application being employed (10-19). Study 2-G and 6-C.

My lnterrpritation- Mover of the primary lever assembly - pp1 or 4-direct drove - pick-up the lagging lever and drag or push is indirect-example might be the "5 yard" interval pressure for partial shots.

Explain indirect and direct in those sections? ......No can do. Homer's got a certain way with words doesnt he? Might need Yoda for that one.

My current state of understanding cant be found in the good book, (which is never a good indicator) but to paraphrase 7-11. ( I wont use quotation marks cause im playing it pretty loose with the words. My apologies).

Power flows from its source (the accumulators) and must be exerted against something (the pressure points) for direct drive of the clubhead through the impact interval. Lag pressure sensed at the #3 or anywhere else since it is a product of inertia only, not thrust, is indirect drive. For its source doesnt flow from the accumulators. It isnt "driving" per say, thrusting. It is however directing and providing sensory feedback for thrust regulation. Geometry and physics combined.

Yoda's gonna puke when he reads this probably.

You explained it well. How does this sound? Accumulator #2 when activated using PP#2 is Direct Drive. When #1 Activates #2 throught the #3 PP, it's Indirect Drive. Hmm? I'll check that against the book and return.

So, when the #1 Accumulator Uses the #1 PP to Activate the Primary Lever, it's Direct Drive. I have no clue why it's called "Passive Direct Drive" for the #2 Accumulator for Swinging, because as far as I can tell, the #1 Accumulator is "Simply Passive".

10-11-0-3 is over my head. I'm going to need a club and do some work.

Would this be ref. sequenced release and simultaneous release??

ALSO

There has to remain some pressure, passive is sufficient, or the whole assembly will want to swap ends - an arrow flies heavy end forward- loose the lag and the system looses control and wants to swap ends, "ground loop" so to say. ( There is some physics to ponder)

Here is another reference to "Direct" and "Indirect" Drive. Indirect Drive is exerted against Clubhead Lag. Now I have a bunch of stuff to figure out. Clubhead Lag is that Slight Flex in the Clubshaft that allows feel of the Clubhead.


Quote:
7-11 PRESSURE POINT COMBINATIONS Fundamentally, Power must flow form its source (the Accumulators) and must be exerted against something (Pressure Points) that will directly or indirectly drive the Club through Impact. The “indirect” drive is exerted against “Clubhead Lag.” So in every Stroke, Clubhead Lag must be assigned to some Pressure Point. The “direct” drive normally uses the remaining employed Pressure Points. See 6-A and 6-C.

There are only four Pressure Points but they can be used in any desired combination – using one, two, three or all four Points. As with Power Accumulators, this produces 15 different combinations. Each Power Accumulator normally actuates its “same numbered” Pressure Point and each Accumulator has its own Loading procedure, as explained in Chapter 10-11.

Maybe this will help. Or not. At least it provides information that gives pause to some discussion.

ps. Can you see, from the data, that PJ is a swinger??
