Scale revised for Sport Bowling averages

ARLINGTON, Texas – For the 2012-13 season, the United States Bowling Congress has updated the scale used to adjust the averages of Sport Bowling league members who compete in standard leagues or tournaments.

The USBC Equipment Specifications and Certification team determined the changes to the Sport Bowling League Adjustment Table were needed after analyzing data of bowlers in Sport and standard leagues. Research continues to show a bowler’s average on the more challenging Sport Bowling conditions typically will be lower than on standard conditions.

The table should be used if a bowler only has a Sport Bowling average and wants to compete in a tournament or league under standard conditions.

“The Sport Adjustment table was put into place to ensure the competition in leagues and tournaments conducted on standard conditions are equitable,” said Neil Stremmel, USBC Managing Director, National Governing Body. “We continuously examine data to see if the variance is significant enough to warrant a revision of the table, and our recent analysis showed we needed to make adjustments.”

The Sport Adjustment table last was revised for the 2008-2009 season. The new mathematical model was developed based on the most current data available from bowlers who had averages in both sport and standard leagues.  It is the best representation of the difference between sport bowling averages and standard averages.

The adjustment is not considered a re-rate, but an adjustment to what would be expected of a bowler during competition on a typical league and tournament condition, and does not supersede a tournament director’s ability to further adjust a bowler’s entering average per USBC Playing Rule 319. 

The new Sport Bowling League Average Adjustment table is available in the 2012-13 USBC Playing Rules (Rule 202a) and is posted online.
