John: I think they will.
Here's why:
When good things happen (i.e. growth), it's the truth.
"Look at how Jehovah is blessing the work!"
When bad things happen (i.e. negative growth), it's the truth.
"It was prophesied, the love of the greater number will cool off."
So, that's why they don't have to fudge the numbers. They have an excuse for both scenarios.
