Calculate a bowling handicap and the adjusted score it produces.
Handicapping brings lower-average bowlers closer to the basis so leagues stay competitive. A percentage below 100 leaves a residual advantage with the stronger bowler, which is deliberate. The handicap percentage is what determines whether a league rewards raw skill or consistency relative to your own average.
