So it seems common to read about a 'good' stroke and how it determines the action you can get on the CB. I was hoping someone could explain what happens on a 'bad' stroke that is limiting to the CB's potential action if the cue tip is only in contact with the CB for a miniscule fraction of a second? Is it simply that the cue tip is not hitting the CB at the point you are aiming at pre-shot or are there other factors? I think the BHE thread in the Aiming section is starting to touch on my own question (swiping vs BHE)
