Why doesn't the WTBTS just lie and increase the published amount of people who attend the Memorial? Who would know the difference? The same with the amount munching on the crackers and sipping the wine. Why show an increase which goes against what I have been taught my entire life. Who would know if they showed a small decline each year? If they would just decrease the amount by 100 per year they could have gone on for over 80 years and all of the old timers would have been dead. Perhaps they are showing increasing numbers for the anointed to change a doctrine in a couple of more years.
Plausible deniability can only go so far to placate cognitive dissonance. Watchtower's upper-tier hierarchy is probably perfectly fine manipulating numbers to please themselves (effectively: mental masturbation). But this upper-tear depends on lots and lots of up-and-comer middle-tier worker bees to keep the engine of its religion business churning. These middle-tier workers have access to everything the upper-tier has access to, only in a more diversified fashion. Hence for Watchtower to intentionally misrepresent values as suggested, it would likely cause a huge schism.
