OrphanCrow brings up a valid point about the hours reported and even the active publishers. For example, I turn in a FS report and haven't actually participated in any form of FS. Why? Because it's less hassle to do it that way then to go "inactive" and deal with questions. When I was the secretary, I know for a fact that people were making up time. But, there's really no way to police it. The person could say they "informally" witness to a neighbor/workmate/someone in line, etc. You simply can't verify the information.
Which begs the question of why they report hours at all. They do it to 1) rank the members of the congregations "spirituality" and as a qualifier for additional responsibilities, 2) because if they don't force a report, members won't go out at all, and 3) likely some sort of proof that they are indeed doing charitable work in countries that require that as a condition for tax exemption. That doesn't apply in the US since religious organizations have tax exemption and there are just a few things that would knock that out. I would imagine this is not the case in some countries.
The hours are likely way over inflated and active publishers are as well. However, baptisms can't be faked. When you see that number decreasing, then they will have real issues.
How many remember when the branch numbers were published monthly in the Kingdom Ministry? They went from that to highlights to nothing. As the numbers start to be negative in the future, look for that. It seems they are already doing it if they don't publish branch numbers.
Also, how many remember when they would put the reports in the middle of a WT and the congregation would make comments on various aspects of the report? LOL - we know why they don't do it now. Hard to get excited over a less than 2% increase isn't it?
