It's only a system until learned, then its second nature, feel and touch, the system is hidden in the backround.
Survey the situation; pre-stroke the cue while standing over the shot feeling the weight of the cue.
Use the weight of the cue for 1,2,3,4 click with combined spin or wherever you will strike the cue ball and be done with it, you feel it, you hear the click.
When learning speed a lot of thought goes into it, you feel it, you hear the click.
Once learned it's hardly a thought, it’s a glance and a feel, second nature kicks in.
Like anything else learned in life it's the repetitive practice that takes you to second nature.
"The cue ball is King"
Lebron James on the winning shot.
I am supposed to make that shot, I have been practicing it since I was a little boy and we still practice it every day.
I doubt he thought about the shot with one second left, second nature did the thinking for him.
