In the first three editions, the 6-H-0 Imperatives were simply "the three most troublesome features to master." However, in the 3rd edition, these three Imperatives were further described as "Hand Imperatives". No doubt, this was to differentiate them (as a group) from the five "Basic Imperatives" introduced in 2-0 of the 2nd edition (and later expanded into the Three Basic Essentials and Three Basic Imperatives of the 4th and subsequent editions).
Then, beginning with the 4th edition, things took a real turn: Homer Kelley began to use 6-H-0 as a "curriculum" for learning Educated Hands, and he deemed that curriculum "imperative". He maintained the original three Hand Imperatives, but stated them in different words and in a different order. Plus, he added two more items to the list.
In reviewing 6-H-O of the 7th edition -- the Curriculum for Educated Hands -- I note that one of the three original "Hand" Imperatives (and now one of the Three Imperatives) failed to make the cut. That would be Clubhead Lag Pressure.
From 6-H-0 of the first three editions:
"ALLOW NOT THE SLIGHTEST UNINTENTIONAL CHANGE OF LAG PRESSURE POINT PRESSURE." [Emphasis Homer's]
From 6-H-0 of editions four through six:
"Avoid unintentional change in Pressure Point Pressure."
From 6-H-0 of the seventh edition:
--
So, Clubhead Lag Pressure -- The Second Imperative (2-0/B/2); Clubhead Control (1-L/B); and no less than The Secret (6-C-2-0) -- has been eliminated from the now "indispensable" curriculum of Educated Hands. The Flat Left Wrist (Clubface Control / pick a Zone ) and Delivery Line (Plane Line/Clubshaft Control) remain.
