The CMA is calculated from the following:[1] [2] CMAs scale from 3.00 to 12.00, any rider scoring above or below these values will be awarded the maximum.
These averages are used in leagues such as the British Elite League to identify heat-leaders for the purposes of choosing which riders to enter for each race.
At the start of a season, a rider retains their last recorded CMA (or assessed CMA if they have never previously established one) until they have competed in six home and six away matches.
These are subsequently updated each 1 and 15 day of each month onwards.
A rider that has no recorded average will receive an indicative CMA for the start of the season that is assessed on their prior experience in the sport.
