"Tracking in this case is complicated by the fact that surveys are generally conducted over many weeks; in the case of The Hunt, the new trailer and release date were only announced a week ago."
That's not really accurate. The Hunt wouldn't have debuted on tracking until today, anyway, so the fact that the new trailer and release date were announced a week ago isn't relevant. That didn't affect its tracking at all, at least from a process/methodology standpoint.
