OK, I think that's in my noggin - the rest of the components that make up the human golfing machine all vary from person to person and from swing to swing, but they must comply with the three imperatives. If you do those things right, the ball should go where you've programmed the machine to send it. Sound accurate? Sounds Good!

Maybe I'm just giving these items too much importance, but I'm still curious why he would call out those three things at such a high level. Do you have any thoughts on this? Is it possible he's identifying three things that have great influence on other components? If you do not execute those three things as intended, it's going to be awfully tough to consistently execute quite a few of the other selected components as intended, no?

I see where you are going with the thought process- which seems logical to me- your thought process that is.

I would say it all flows from 1-L. So in 2-0 under essentials and imperatives you've got to keep the Machine concept and everything he talks about in 1-L in reference. The Essentials and Imperatives in 2-0 is really the segway - he's building the bridge- that is - he is referencing, reviewing, and summarizing the Machine Concept- what a precision stroke includes based on the 1-L The Machine Concept and then the first paragraph after the Basic Essentials and Basic Imperatives leads us from the Chapter 1-L Machine concept right into the science- and the geometrical relationships. So based on this Machine Concept- here are the scientific application and verification and elaboration of that Machine Concept- it's his logical progression.

So really the essentials and the imperatives covers all 21 items in 1-L- you could essentially check them all off the list with those six items. Now, looking at the essentials and imperatives in regards to or in relation to the Human- sure you could have a little head movement, not be perfectly balanced like the machine, maybe have a little variation in clubhead travel i.e. rhythm but as long as you have the imperatives you'll be Golden. So the Machine is perfect on all six items- Stationary Head, Balance, Rhythm, A "Flat" left wrist, a lag pressure point, straight plane line. But in the Human application- the essentials can be off a little as long as you are accomplishing the imperatives. But all six are the important characteristics of the Machine.
