Not to mention the numbers are a total lie anyway.
I'm not so sure about this. I think if the bOrg was fudging the numbers, one of the ones they would work on is the memorial partakers. There is nothing to suggest they are doing this.
And in reality they don't need to do this anyway. Even if the numbers started to decrease, there is an excuse for that. They can just say that as the bible says that before the end, "the love of many will grow cold", and so this exodus is expected, "Jehovah is cleaning his house before the big A", there are several different palatable excuses that the drones will swallow without even blinking.
