So it looks like THG will make around 18.7M for its 5th week, give or take 0.1M (I prefer doing weeks instead of weekends).
That's around a 30% week-to-week drop (the previous two week-to-week drops were around 42%). With the IMAX re-release, I think another 30% drop for the upcoming week is reasonable.
Scenario 1: So if we extrapolate this forward (30% week-to-week drops from here on out), then it'll hit 400M some time during the 12th week and close around 405M.
Scenario 2: If we make the TA opening week drop 40% (but keep all other weekly drops at 30%), then it'll hit 400M after week 18 and close just a wee bit over 400M.
Scenario 3: If we make the TA opening week drop 40% and make all subsequent drops 35%, then it'll close a bit under 397M.
Scenario 4: IMAX doesn't help much, and next week drops 35%. Avengers takes a big bite and THG drops 45% during the TA opening week, and all subsequent drops are 40%. In this case, THG will close around 390M.
I used to be on the 400M-is-too-remote bandwagon, but now...
