MovieMan you can't just handpick the worst days from King Kong's run and say Rogue One will perform like that, and then completely ignore the other days and say the end multiplier will suck.
If Rogue One follows King Kong it's gonna end up with a 4.36 multiplier. Of course I don't think it will reach a 4.36 multiplier, but if you select one particular week-end, or a set of weekdays, where King Kong underperformed for some reason, apply that to Rogue One, and then proceed to ignore the rest of the run...
it just doesn't work that way
Plus, you know, the whole King Kong is 11 years old so maybe its daily patterns don't apply to a 2016 movie anymore... kinda thing
On that subject, I also recall last year lots of people (myself included) falling into the trap of comparing TFA dailies with LOTR dailies. LOTR is just too old, movies perform differently now.
