I find it hard to believe the numbers are as high as the WT corporation suggest. They are a lying bunch of ass holes under cult delusions which is the primary reason for their bad state of affairs and stupid business decisions, they cherry pick facts and fudge figures all the time to support their agenda. So I'm in convinced that they are not being factual in reporting the figures, they must be first processed through WT corporation's agendas before being put in print. I'm sure the brother that collects this data has to go to the GB in a private session to give them the real figure and then the GB make up the number and give it to this brother for printing.
With all the reports of assemblies with nobody getting baptized or perhaps 1 nine year old I find this figure bogus.
