One thing I noticed when shooting with GJM is he has insane twitch reflex speed. It is not a normal thing. Being able to apply that in activities like shooting and flying are a good place to use them. I did a class with a SEAL instructor at one point. Like GJM the guy had amazing hand speed......and could shoot at a very fast rate. Unlike GJM, he couldn’t hit a thing.
I am a big believer in there are some basic human development factors in a lot of this. The key is capitalizing on them. I could practice as much and be more dedicated than Michael Phelps....will never even make an Olympic team.
Back to the original post....it is why working on very defined skills and solid training routines is critical. You need a solid measure of where you are and be constantly improving or at minimum maintaining critical skill sets. Solid measurement testing is a big part of that.
