Here is the hours breakdown posted in the local hall (US, Midwest, semi-rural area) for August, 2011
130 total pubs of whom:
10 reg pioneers
3 Aux pioneers
10 no report this month (good for you! Keep up the good work)
35 report 1-5 hours
35 report 5-9 hours
37 report 10+ hours
Of the 130, 21 are irregular.
The average for the month of August for the non-pioneer publishers was 9.1 hours (slightly higher than the 8.3 hours 3-month average for the same group).
Inactives don't show up at all in these figures.
There you go, the 1/3 1/3 1/3 assessment seems to accurately describe this congregation.
