Answering for myself, not Neil.
Using the definition of feel as subconscious information based on past experience, without having any concrete visualization or thought process.
No, I don't use feel to decide in between shots. If I start with a half ball hit, then slightly adjust, I am visualizing the required CB/OB collision required to make the shot. I might adjust slightly thicker or thinner, but I am visualizing an exact collision and establishing a exact line the CB will roll on.
It is possible that people very experienced go through their aiming process so fast, it seems like subconscious feel. However, if they were to slow down their decision process and accurately describe step by step what they are thinking, it might resemble a specific concrete aiming method or system.
I am a technical analytical thinker. As part of my work, I often have to break down and explain processes step by step to less experience employees. As they become more experienced, those processes happen so quickly you could say it's subconscious, but IMHO, it's not. The detailed step by step thought process is just happening very fast because of past experience.
