Quoted from DaveH:Never. There is absolutely no reason to. My score doesn’t matter unless I’m competing. So why would I need to artificially inflate it by removing the bad balls? If I have a house ball on ball 1, I want to see what I can do with 2 and 3.
I am in this group; with the caveat I did "restart" my JP a few times to test out the raptor lock mechanism.
So NEVER during play, if needed during testing, sure. That should be obvious but some people are super literal.
To me I am stepping up to play a pinball GAME. 3 balls, maybe more. Part of that game is having a rough ball or two maybe. Doing what you can with the rest. Other opinions are valid, but I don't know why I would choose to rob myself of setting a new grand champion score on a single ball or whatever; some of my best games only have 1-2 real played balls. That's pinball baby
