Doc: From a system process, you have identified the 2 basic physical parts of the system. Note the word 'physical'
Included in the system process (and not being picky), there is also mental components of non-shooting and shooting parts of the system that link to 2 together.
Putting them together is the 'cradle to grave' component process from the point when the buzzer goes off.
From a training aspect, one should analyze both the physical and mental process steps. Then...
...if physical is weak, identify the compents to increase or better them as a function of time
...if mental is weak develop exercises to better or increase them in conjuction with the physical.
Here's a far
off the wall example:
...Sit on the toilet with the lid up
...Spit between your legs into the bowl without spitting on your legs and
not looking down.
And no, I'm only smoke tobacco!
It's both both physical and mental
