Amateur Youth Bowlers Tour is determining handicaps through averages in our tournaments. Any bowler who bowls in an event in the handicap division will be using their USBC Standard Composite Average from the last available season, converted to a Sport Average through the USBC Average Conversion Chart, for the bowler's first event only. After their first event, they will have established an average with AYBT and their average from that point on will be the average used to determine their handicap.
