Section 6-M goes into a general definition of the 'release', the sequence leading into the release, and a basic overview of the 2 different types of releases.
BASIC DEFINITION & OVERVIEW
The Release triggers the Power Accumulators into action and starts all the parts of the machine towards the 'Moment of Truth' (impact). All the golfer's attention will be directed towards the downswing sequence, so the full swing will flow smoothly thru impact from the top of the swing directly to the finish.
The Power Accumulators release in the sequence of #4-#1-#2-#3 provided all of the Power Accumulators are used by the golfer.
Any Accumulator number may overlap or replace its preceding number, but cannot precede it.Meaning, instead of a golfer using the sequence 4-1-2-3, they can go, 4-2-2-3. But, they cannot go 4-2-1-3.
There are two release types --- Automatic and Non-Automatic.
Non-Automatic = Drives the hands to their location at Impact.
Automatic = Drives the hands to the Aiming Point.
The non-automatic release is part of the non-automatic stroke. The non-automatic stroke is actually what it sounds like, a swing that is not 'automatic.' Meaning that the golfer should consciously try and perfect each part of the swing and then consciously perfect the downswing sequence and the release of the power accumulators. Homer talks about never 'making a shot', but instead 'make a motion.' So if you want to hit a big fade, don't just try and hit the big fade and instead make the motion that will produce the fade. I think Hogan's slow motion drill is a good way to work on your Non-Automatic Stroke and the Non-Automatic Release.
Once the Non-Automatic stroke is mastered and it becomes a case where the golfer may have one or two swing feels and then they let it rip, the golfer can then push on to maximize things like delay of the release (aka maximizing trigger delay).
So basically, the non-automatic release focuses on the alignments. Getting those hands forward with some shaft lean so you have a flat left wrist at impact that is not bent nor arched.
Then once you get those alignments down and grasp those mechanics, you can feel what it's like when you have the proper mechanics and then you can approach the swing with a swing feel and let it rip.
