...the number most associated with the sport in the middle e.g. 15 for rugby, 11 for football, 18 for golf etc.
As they seem to have a '1' at the start, why not have '15-0'?....the others are for the team numbers/ holes synonymous with that sport. What makes tennis different from other one v one sports is the scoring system, so why not?
