Not sure whether you've been under a rock lately, but they dropped the hourly reporting requirement a few months ago. Nobody except for the true believers are going out anymore and even the latter are taking it a bit easier.
That means a congregation of 150 went from 1500 hours (minimum 10h/publisher) a few years ago to perhaps 50 or 100 hours (10% of their original) and a lot of that is probably parents studying with their kids, or pioneers driving around and doing studies/return visits.
That's like a medium sized restaurant downsizing from a full staff to just a waiter and a cook and wondering why it takes long to get a drink refill.
