I have only been bothered to the point that I would call significant twice, once by a friend who was giving me an ass whuppin, though he couldn't win with the 8 and we were playing tourney match/ even.
The othe was Jeremy jones. I don't recall what the race was to, but he was in no danger of losing! As you might imagine, he stayed in line the whole time and the last few games, had shoot/ stop outs, but he had to walk around, get down get up, use a towel, suck a cig, use a towel, get some powder, look at the shot some more, use a towel...and it was far more painful than reading the past few lines, trust me.
My opinion and attitude that I try to maintain is tha I don't shoot until I am ready, why should I expect to be able to dictate to others when the should be ready to pull ye olde trigger?
