Yes.
If you practice all that stuff, and practice it correctly then you're the guy that can pull the pistol out of the holster, bring it up and when it stops the sights are aligned with each other and the target.
Ever know anyone who could shoot from the hip and hit what they aimed at? I did. He practiced, constantly till part of the draw was body position in relation to the target, hand position on the revolver (old SA Colt), hand/wrist/revolver position/angle to the target. He whipped that gun out, cocked it on the way to the firing position and fired. I watched him shoot a soda can off the fence one night after the sun had gone down enough I could no longer see the sights on my Ruger Single Six. We stopped shooting, headed back to the house, a few steps towards the house (away from the targets) he stopped and said, "I've got one more round in my pocket." After 30 years of working with that Colt he knew, by feel/sound how to turn that cylinder after closing the loading gate so the single round was under the hammer once he'd cocked it. He turned around, fired and the soda can came off the fence.
With the rifle, when you made the decision (when your experience/perception/body work together without you taking the time to think about) to fire on the target your body will turn just the right amount, your hands grab the rifle, your body position becomes correct for the position you will fire from and once your body stops moving the rifle sights/cross hairs will be lined up, the safety is off, the trigger finger is positioned and you take the shot.
Can't say how much of it works for rifle and pistol shooting. Breathing, finger position on the trigger, trigger squeeze, sight alignment, etc.
I used to shoot with an old guy who was on the Navy Rifle Team in the 60's. He used to say, "Never waste time at the range doing something you could have done at home. Think about that and then go do some dry fire drills.
