I just like 2.5x because its easy, pessimistic as it might be, no need for extra math trying to breakdown anything especially the splits which can be wildly different depending on the studio or even the film. I don't know why anyone would want to over-complicate it even more unless they are trying to make things look even worse for a certain studio or film.
As do I. I hope this one continues to chugs along to the 700’s so we can get the sheet out of deadline. At least we’re getting Moana, IO2 and Deadpool.
