[O.B.Left]

OK Ive been thinking about this a little. Couple of things first. Lag in a common golf speak sense is what we TGM types would describe as float loading but with a degrees of left wrist cock perspective attached. Whereas, Like Kev alluded to, Homers Accumulator Lag refers primarily to Lag Pressure at the #3pp which cant be measured visually really, beyond noting the trailing condition of the clubhead. Perhaps if you had a sensor at the #3 measuring the pound per square inch or something.

Accumulator Lag is discussed in 7-19 Lag Loading, where amongst other things Homer says; "Properly manipulated, Clubhead Inertia can withstand all the Lag Pressure anyone can generate."

In terms of degrees of #2, left wrist cock, absent any mechanical arguments against exceeding 90 degrees, Im thinking that you should let the conditions of Release and Impact be your guide. In other words play around with his float loading (Lag Loading) to discover what gets him to his best Release Point. Test it on a launch monitor maybe after you think you got it figured out.

And in this regard Homer does mention degrees of Left Wrist Cock in a way. See 6-N-0, Its a great read but basically the "short quick Arc of Maximum Delay", Snap Release, Maximum Power, is measured in degrees.

"This involves Angular Speed which is measured by the number of degrees of an Arc through which the motion moves per second"

The "per second" part alluding to the Release Point, Travel Time. An earlier Release Point increases the travel time for any given number of degrees to the Arc, with an accompanying loss of power for any given Hand speed. Homer says that doubling the travel time (earlier release) halves the travel rate. To me suggesting that the important thing is not what your guy is doing at Top or in Startdown but what he is doing at Release, so let that be your guide.

Slice, I bet YodasLuke, aka Ted Fort would be the guy to talk on this sort of stuff. Its right in his wheel house.
