I recently finished reading Carl Olof Jonsson's book on the Last Days When?. The information contained in that book details how the society manipulated and lied about information on earthquakes, famines and wars to support their agenda. I see no reason why they won't do the same with the annual figures.
If it suites their agenda they will do it. Isn't funny how on an anecdotal level we are all seeing numbers of witnesses decreasing, yet low and behold the numbers are increasing!. What a surprise too with their recent doctrinal manouvering on the generation an increase in the number of partakers! As some here have pointed out this is just a cynical move to buy themselves more time. I don't see the demise of the organistaion just yet as Gary Buss has pointed out they have a captive audience.
