One of the 3 imperatives is "Clubhead Lag Pressure Point".
That has to happen in the backstroke/downstroke, as the club gets loaded on the way up and this is felt in one (or more) of the Pressure Points - preferably #3 PP. And the lag (load) has to be stored and delivered down to release and impact without losing the lag (= throw away) by maintaining the feeling/pressure in the PP.
In other words, the lag pressure is the effect of the club inertia resisting acceleration, so you must keep accelerating in the downstroke and through impact (as a feel at least, as the impact will effectively cause deceleration) and not "give everything you have from startdown and then freewheel to impact".

Thanks for the additional information. The more, the merrier.
