I remember some Circuit Overseers stating what "Exemplary" should be for most brothers. They were to be "Visibly taking the lead"- Code word or SEEN and above National AND LOCAL field service averages. Some halls had 5-6 hrs for ANY jobs in the hall. 10-12 hrs to be appointed. 15 hrs to be appointed if he was NOT a brown Noser.
I found it weird even then, that a car load of brothers could go out every week together and all turn in such vastly different service time. It would range from 5-15 hrs per month. So the one brother (with 5hrs and super strict conscience) could not run mikes, but the guy who turned in 15 hrs (and lied) was "exemplary".....???????? (and yes in these cases I did check if they were "out", had studies, or other time).
The whole concept has no basis in anything from the bible or ANY relation to being a good Christian or leader.
It is a good thing it discourages the good ones so they "See the light- tatt" and leave.
