Well, if I have the ball with me, and don't change, shame on me. If the ball is at home in the magic closet, too bad. I gotta make do with what I got.
As far as adjustments go, if I make one, and get an unexpected result, I can either move back, or keep adjusting. I have choices. Sometimes the adjustment can be more costly - sometimes it's a little less trouble than I would have been in otherwise.
For example - the ball is starting to dive into the pocket, hitting high flush. I just tripped a 4 pin. In this house, once the lanes start to go, it's a race to see who can move fastest. So I move 3 boards left with my feet, and probably the same with my target. Oops - I left a bucket. Well, much better than the 4-9 or worse that I would have left if I'd stayed where I was - and I can always move back one right to get to the pocket.
