7-11 (Pressure Point Combinations)
'Fundamentally, Power must flow from its source (the Accumulators) and must be exerted againt something (Presure Points) that will directly and/or indirectly drive the Club thru Impact.' - Homer Kelley pg. 104I can't tell you how important I think this statement is to making a swing that produces precise results.
The power comes from the Power Accumulators and those Accumulators are exerted by the Pressure points. One thing that has improved my swing tremendously is that I now have proper 'extension' after impact. Here's a pic of Zach Johnson with proper extension in the follow thru.
In TGM terms this is known as proper Extensor Action, where the right arm has straightened in the follow thru and that stretches the left arm which has already been straight throughout the downswing.
As this was one of my problems, I erroneously thought that I had work on actively extending my arms in the follow thru. But what I really needed to do was to have the proper lag pressure at impact which was exerted by the #1 Pressure Point in my right hand. That exertion thru my pressure points would, in my case, feel like it would push my arms 'into extension.' Without the pressure points exerting the lag pressure, the flip would come into play and I didn't have enough 'umph' to extend both arms into the follow thru.
That is what the quote above represents to me.
A golfer can use one or any combination of pressure points. This produces 15 different combinations.
Each Power Accumulator normally actuates its 'same numbered' Pressure Point.Meaning that the number PP and numbered PA are 'connected' to each other.
#1 PP = Lifeline of the Right hand where it touches the left thumb. The #1 PA is the folding and straightening of the right arm which is 'triggered' by using the #1 PP.
#2 PP = Last 3 fingers of the left hand. The golfer will use the #2 PP if they are trying to use the #2 PA, which is the vertical uncocking of the left wrist.
#3 PP = BASE JOINT of the right index finger. The #3 PA is 'transfer power' which is actuated thru use of the #3 PP.
#4 PP = Where the upper left arm and left side of the body meet. Using the #4 PA by 'blasting the arm off the chest' requires some 'snug' left side connection.
So, if you're a hitter you need to focus on the #1 and/or #3 PP's and their role with the #1 and/or #3 PA's. If you're a swinger, you should focus on the #2 and/or #4 PP's and their role with the #2 and/or #4 PP's. Obviously, you can use any combination of PP's, but if you're trying to develop your Stroke, you should try to get your focus on those PP's depending on whether you are a hitter or swinger.
That's a big reason why I feel you want maximum pressure of whatever pressure point you choose at impact, because it produces maximum power accumulator activation and maximum lag pressure.
7-12 (Swing Center Tripod)
Swing Center Tripod has to do with the pivot action and the 'stationary' head. Homer believes that the golfer should have a 'centered' and stationary head. Sort of imagine the golfer from the Face On view as a trip with their feet being the tripod legs and in the middle of tripod is the golfer's head.
Here's a 2-frame pic from Justin Tang showing an 'incorrect' moving head on the left and a 'swing center tripod' on the right.
