There is actually no rerate for Sport averages,so why would they do RW&B. The ABC went to all the trouble to do the average chart for sport to league averages. Then when I did rerate based on that chart was told the rules prohibit rerating based on the average being from a Sport league. Now I remember when this all started that was why averages would be noted if the league was a sport league. I guess bowlers would not take a chance and the concept was dying,so they changed the rules.
