For reference, I have been incubating from the following sections on acc #3: 4-D-0; 2-P; 2-G; 7-18; 6-M-1

Here is a thought that I cannot find stated explicitly in the book, but I think it is valid and relevant to this discussion:
Increasing Accumulator #3 enables greater handspeed because it allows a smaller radius (less effective mass) for the clubhead at the top (or end). Accumulator #2 (left wrist cock) has a maximum limit (about 60-65 deg for me from level to fully cocked). If I add 40 deg of acc #3, that means that the angle between the left forearm and clubshaft at the top is 100-105 deg., which means at start down, the clubhead is closer to the center of rotation than the hands, or greatly reduced effective mass, which translates proportionately into increased acceleration from the same amount of torque. Increasing acc #3 should have a greater affect with longer clubs. It seems to me that acc #3 would probably have a greater affect for swingers than hitters, because swingers go to end and have a quick start down, giving the hands more time to accelerate with the lower effective mass.

Also, 6-B-3-0 states that "Accumulator #3 Hand Motion (4-D-0) is "Clubface Control," "Rhythm Control" and "Roll Power Control" of the Right Elbow". This seems to infer that increasing acc #3 increases control of the roll of the left wrist. The swingle (2-K) seeks its inline condition, so CF helps to pull acc #3 inline at low point, if rhythm is correct and CF is not manipulated.
