Before anyone takes this too seriously -- and it is surely too late for that -- I should point out that they did nothing to disambiguate the length of the movie. It may not be the coughgeist but the ... er ... timegeist (they should have a german word for it).
Anyway, the point is, coughs per hour would help us know if audiences simply favor longer or shorter movies at different points in time.
