For me, the onus is on holding forced slaps between a few short dynamic moves at one's near single max grip to induce aggressive concentric action for the muscles. I find this quite different on the fingers from slow strength moves that are developed in the strength phase using lock off's etc.
I was doing 2 sessions lasting about 5 mins per set over 3 sets per session with 10 min rests between sets with a minimum gap of 2 hrs between each session to achieve a non lactic state at near full power as possible. I also mix up the moves in a vertical sequence to get the most from each attempt as it seems to help avoid lactate build up during set.
