i have consistently averaged around 186 the last 4 years and every 3 months i bowl in a county tournament for fun with co-workers. Well i shot a 814 in the last tournament, so i must have been sandbagging for four years? People go up and down and have moments of greatness and moments of crap. Why do you think the USBC never does anything about it??? I had the luckiest day of my life bowling, and im sure many people at the tournament were tempted to pull the "sandbagging" card and complain. The rule itself of sandbagging is ambiguous, meaning it's unclear or open to interpretation. I'd be pissed if someone accused me of sandbagging when i wasn't and had the nerve to report it to USBC. Just bowl and beat someone scratch that way there is no doubt who may be "sandbagging."
