Bonus Play Success Rates
This is one for readers with insatiable analytic appetites. It is the question of who is the most successful at calling the bonus shots, i.e. assessing the situation after half the bowls have been delivered. Now there needs to be some normalization applied in calculating this. A very strong player might win all ends played and will therefore necessarily make 100% of the bonuses called. Conversely a very weak player who loses all ends played cannot have better than a 0% success rate. Similarly a player that makes 50% of ends played and calls bonuses entirely randomly is likely to make around 50% of the bonuses called. The bonus calling success measure is the difference between the bonuses made percentage and the ends won percentage. We call this the success delta and participants who have played three or more matches are ranked according to this in the table below. Note that each player in a pair is assigned that pair's bonus shots regardless of which individual may have been more responsible for choosing the bonus ends.Updated Dec 5.
