The better your habits, the more available focus there is for the target. Duh!
Another breakthrough for me to explain available focus:
Focus is a see-saw effect between the muzzle and the target. You can’t give a target more focus than you have available to give.
Just like shooting well is not an achievable goal, giving more focus to a target won’t work either.
When you have to think less about what you are doing with the gun, then and only then can you give a target more focus.
