Gonna make a guess based on issues making the money ball. I missed the money ball far more than I should have for years. Finally figured it out. Every other shot, I played to make the ball and get shape. Money ball, I didn't need shape so I just played not to scratch. I was playing the money ball shot differently than any other shot!
I cured my problem by choosing a spot for shape when I shot the money ball, then it became just like any other shot.
For practice, shoot the spot to spot shot but put a gate to go through. Something else, put a ball near the cue ball's path. Keep getting it closer until you can almost rub it without the cue ball getting sucked into it.
99% certain your unconscious is causing your issues. Need to train it not to anticipate.
