Here is another reference to "Direct" and "Indirect" Drive. Indirect Drive is exerted against Clubhead Lag. Now I have a bunch of stuff to figure out. Clubhead Lag is that Slight Flex in the Clubshaft that allows feel of the Clubhead.

7-11 PRESSURE POINT COMBINATIONS Fundamentally, Power must flow form its source (the Accumulators) and must be exerted against something (Pressure Points) that will directly or indirectly drive the Club through Impact. The “indirect” drive is exerted against “Clubhead Lag.” So in every Stroke, Clubhead Lag must be assigned to some Pressure Point. The “direct” drive normally uses the remaining employed Pressure Points. See 6-A and 6-C.

There are only four Pressure Points but they can be used in any desired combination – using one, two, three or all four Points. As with Power Accumulators, this produces 15 different combinations. Each Power Accumulator normally actuates its “same numbered” Pressure Point and each Accumulator has its own Loading procedure, as explained in Chapter 10-11.
