I feel the WT corporation has reached its point of no return during the first decade of internet existence and that the WT's dishonest published figures of growth were an attempt to keep the downward spiral from its members alerting them to the Organization's demise from erroneous end of the world predictions.
So that any graphs that one can make from the WT corporation publish figures should be enclosed with the caution that: "these figures are very biased from a cult with a proven high degree of denial and outright delusional falsehoods bias, and are probably a lot worse then they will admit to".
Which I think explains why the Kingdom Hells are being sold like hot cakes while the societies figures don't show that much negative growth. They are stuck in denial and cherry pick made up facts to forecast future events. Not very good for making solidly business plans for the corporations future survival. All this mental fog for guiding how asset are to be used, not very wise.
