Too many, but we rerated one this season, so its not the be all end all of how to sandbag. Took years of history on this bowler in multiple associations, leagues and tournaments. So its not easy or quickly done. Keep in mind that these are bowlers that hit 2 to 4 tournaments a month, its like a second job and income for them.
Purposely keeping your average low for the purpose of entering handicapped tournaments is not right. No matter if you bowl in a tough house or not.
