Pilot, do you have an understanding of Extensor Action? Do you use it? How "heavy" or intense was it on your shot?

As I understand and try to use Extensor Action, I try to keep a gentle but steady pressure on the base of my left thumb with my right hand. The feeling I am looking for is like a small child tugging on your hand, enough to be noticeable but not enough to make you tense up and resist it with the left arm. It is something that I have been working at since around February. I sometimes lose it when I swing too fast or mess up the right forearm takeaway. But when it is there you can feel and hear the difference in the impact.
