Yes, and because it involves your mind as well as your eyesight, what happens can vary from time to time. It was crazy that I couldn't "see" the shot I have shot I suspect thousands of times! One reason I shot it was I didn't want my opponent to think I was playing games with him. It was a couldn't miss shot, or so it seemed. Jawed it and left him the hanger.
Talking to everyone about those who choke: Something else can happen too, chalking up the victory too soon! More than pool, I remember a pistol match. I was shooting eight inch steel plates at ten yards after shooting harder stages and everyone had already ceded me the victory. I was shooting a pistol with a red dot sight and I broke the shot as it settled on the plate only about an inch below the top of the plate. After I broke the trigger, I relaxed. My arms or whole body relaxed enough that in the split second, a few hundredths or less with the titanium and other lightweight components in the pistol, it had time for the barrel to float up before the bullet left the barrel and the plate still stood! Cost me an event but I never again celebrated too soon!
