They do have a 5 pin drop rule and 10 pin increase rule. My doubles partner had a 230 book in 2001-2002, a 216 in 2002-2003, and a 220 in 2203-2004. He came in with a 225 and we had no problem with it. Last year I had a 171 book for 2001-2002 and a 189 for 2002-2003, I reported the increase and was brought in with the 189.
They also require you to report any tournament winnings of over $300 for a single event. I had to report it this year for both ABCs and this tourney. I won $327 last year in CA Women's State for a tie for 2nd in singles.
On the form I had to fill out for the reporting of prize winnings, the bottom is for average. They ask if you have 21 games or more in tournament play with a higher average than book. I don't know if this guy has been bowling the tournament regularly or not. If he has, then I suspect that when they do the final checks it should be caught.
Too bad all bowlers don't have the pride and integrity. I guess until the day comes that bowlers enter tournaments for the challenge and not the money, this will be a problem and such bowlers will be fuel for rumors.

Age is only a state of mind. Since I lost mine years ago, I must be really young
