Always an interesting topic this....
If we set, say a certain percentage - lets say 40 % of calls outs must be attended, for a person to remain active, we face the following problem:
Brigade A, a rural brigade is called to, and attends a total of 5 calls in a year. All members of the brigade (all 7 of them!) attend all 5 calls, meaning all members attend 100 % of the calls.
Brigade B, and busy urban fringe brigade, attends 400 calls a year. One of their members attends 100 of those calls, meaning that member only attends 25% of the calls of the brigade.
But, brigade A members with 100 % attendance rate only do 5 calls, but are considered to be active, but the member of brigade B, who attends 100 calls (eg 95 more than brigade A) is not considered active under a system such as this.
So, by simply setting an particular percentage of callouts to attend, we create a very inequitable system.
So, if we were to set limits, it would need to take into account far more than simple numbers.....
