The Beauty of 12-5

[Yoda]

Trig,

Can you please highlight some of the pitfalls that people fall into when trying to utilise 12-5?

We're talking about the three-stage Basic Motion Curriculum: Basic Motion (12-5-1); Acquired Motion (12-5-2); and Total Motion (12-5-3).

The first pitfall is failure to observe the boundaries of the respective stages. For example:

The Basic Motion is two feet back and two feet through. Unless this motion is made on the Putting or Chipping green, the Stroke is almost always too long. On the range, even after I demonstrate the correct length (and hit the ball no further than about thirty feet) the first thing I see from the student is a pitch shot. The Hands swing back at least waist high and finish at least waist high, and the Clubhead is above the Hands on both ends of the Stroke. This is Stage Two (Acquired Motion) not Stage One (Basic Motion).

So, in practicing Stage One and even Stage Two, go to the short game area. Give yourself a target just a few yards away. This is a Putt or a Chip Shot (with, at most, a few yards of carry). Practicing Stage One on the range is a very dull and expensive way to get the job done. But if you have no alternative, visualize a chipping green and a near target, otherwise your Stroke will be too long, and you will exceed the Basic Motion's boundary.

The guy from Nashville had the same problem. But, I gave him such a short chip, he couldn't take it more than two feet back.

The other thing to note is Stage One has zero pivot.

Stage Two has zero pivot EXCEPT shoulder turn. Stroke length takes focus just as in Stage One and the right forearm goes no further than parallel to the ground.

So I think the major pitfalls are making the stroke too long and using pivot/too much pivot in Stage One and Two.

How many Accumulators should one use for 12-5-1?

How many Accumulators should one use for 12-5-1?

Good question. Homer explicity says to zero out accumulator #3. So the answer is less than 4!

If I think about it, there is no wrist cock either, so that eliminates #2.

I think the answer is 2. You should use accumulator #1 and #4 while executing 12-5-1.

Trig,

I was trying to figure out how Acc. #4 was involved in a stage one stroke. Then I referred to 6-B-4-0 and read this; "Left Arm Power in any form or amount can still be considered #4 Accumulator Action."

So, yes Accumulator #4 is involved in the two barrel stage 1 motion.

I learned something today, now back to answering the pro shop phone.

Hmm...so for 12-5-1, when Homer lists Acc #4, was he referring to independent Left Arm Power, or Body Power? The latter will clearly make the zero pivot requirement harder to achieve. But it also has mechanical advantage (which is pretty irrelevant for 12-5-1).

We're talking about a Stroke that is two feet back and two feet through. Body Power? I don't think so!

The Basic Motion of 12-5-1 is a One Accumulator Stroke (Single Barrel, 10-4-A). And that one Accumulator is an Arm Accumulator, either the Left (10-4-A-4) or the Right (10-4-A-1). If the player chooses to use "Left Arm Power in any form or amount," then the Thrust is Centrifugal (6-C-0-4) and the Stroke is a Swing. If the player chooses to use the Right Arm to drive the Primary Lever (Left Arm and Club), then the Thrust is Muscular (6-C-0-1) and the Stroke is a Hit.

Both Accumulators are referenced in 12-5-1 because both Arms are in Motion -- one Active and the other Passive. And that Motion is identical, no matter which Arm actually drives the Stroke.

How many Accumulators should one use for 12-5-1?

Stage One of the Basic Motion Curriculum utilizes only one Power Accumulator (Single Barrel Stroke). And that Accumulator must be an Arm Accumulator: Either the Left Arm (#4 / Pull) or the Right Arm (#1 / Push). The Hand Accumulators -- Left Wrist (Cock and Uncock) and the Left Hand (Turn and Roll) -- are introduced in Stage Two (Acquired Motion).
