Nothing has been accurate since the 60th started. DLR is pretty much busy all the time, and when it's not busy Disney comes up with new promotions to bring in crowds. For example, Food & Wine was announced on short notice this year and attracted people and shrunk the walkways in DCA. AP Appreciation Month was also announced a few weeks before it happened and also attracted crowds. If attendance does dip after the 60th, the crowd calendars will probably still consider the high crowd levels that it drew for the last year plus. The next annual theme that Disney starts after the 60th ends in Sept might be really popular too, but crowd calendars wouldn't know that until it happens, which it won't until after the 60th ends.
