The problem with bowling leagues
Bowling is America's number one participation sport. Many bowlers are league bowlers. Most leagues are handicap leagues.
Setting the proper handicap percentage is critical to a league's success. But no single handicap percentage can be optimal for all leagues. Even a change to the season length can require a handicap percentage adjustment to maintain league balance. Few leagues make such adjustments, and those that do must guess and hope they've gotten it right.
As a result, unfair leagues are everywhere. They are likely the rule, not the exception. Once bowlers suspect their league isn't fair and they have little chance for success, they usually drop out of the league. So unfair leagues are as bad for bowling centers as they are for the bowlers themselves.
