I've seen nothing from Daybreak on this, so it all seems to be speculation. Unless someone from Daybreak would care to comment on it now?
You don't need to rely on Daybreak. Read the writeup I wrote (posted on Alla under the progression FAQ somewhere, and on these forums somewhere too) and do the math yourself, the only time it's ever been wrong is when the voting system bugs out. Almost none of the DBG staff really know how the voting unlocks work anyway. Even in Ngreth's post linked in this thread, he acknowledges he doesn't know why it works the way it does (although he did get the dates correct.)
