Sport for all
It would be entirely too predictable if the same people kept winning! For this reason, some internal competitions - plus at least one external one - are scored using the Bayley Handicap System. This allows shooters to, in effect, compete against their own average.
A shooter's average score is calculated by taking the average of the best five out of their last six cards. Their gun score - the score they actually achieved on the range - is then adjusted mathematically with reference to this to produce a handicap score, and the shooter with the highest handicap score wins.
