Congregation I was in covered a huge area and had close to 50 territory maps. The whole territory was never fully covered. Service group overseers had favorite territories so those were worked often. The least favorite were hardly ever worked. Sometimes the person in charge of service wasn't even prepared with a territory so they would just send the pubs to whatever territory off the top of their heads....so some sections were overworked. Even during campaigns the whole thing was not done. (even with 30+ RPs and a large amount of auxiliary for the month)
JWs like to say they are the most organized, when in reality it's not so true.
