Some interesting posts.

Don't know why it is imperatives vs essentials.

Do know that in version 2 and 3 it had
The 5 Imperatives showed up in the 2nd Edition:

1) Stationary Head

2) Balance

3) Rhythm

4) Flat Left Wrist

5) Clubhead Lag

Then in the fourth it became the first 3 as essentials and the last two plus the addition of the plane line as the 3 imperatives.

In fact somewhere I read that there was actually 8 imperatives back then.

The logic presented machine vs human, has some potential maybe.
