I'm definitely on the high end of the nudging scale. However, I never take off the plumb bob because there are times when I want to tilt the machine, usually when I'm frustrated because I'm playing horribly and I'd rather get the next ball started quicker than wait for a measly 12K or so of bonus to be added to my score. That said, I'd never do to anyone else's machines what I do to my own. On my machines, I'd estimate over 95 percent of my tilts are deliberate.
