I use a combination of pp#1 and pp#3 to time the release and to tune the degree of overlap between Acc#2 and #3 release.
I use pp#1 because I want to: Down stroke loading, timing and shot making. I use pp#3 because I can't avoid using it if I use pp#1. I driveload, but I prefer to let CF release accumulator #2 to the largest extent possible.
Hmm... maybe I should try to increase the overlapping grip with one more finger? That should enable pp#1 increase and pp#3 reduction shouldn't it?
Yes - and I don't do anything actively with pp#2 - except for what the subconcious will do to help me get the club correctly through the ball when something somewhere in the stroke is less than 100% OK.
