Comment (by markfilipak):
May I point out some features of 5-5-5-5 pull-down v. 2-3-2-3 pull-down?
Even at 60 FPS, 2-3-2-3 pull-down (actually, it becomes 4-6-4-6 pull-down)
has +/- 5% cadence @ 12Hz, and 40% combing @ 6Hz.
5-5-5-5 pull-down has no cadence and combing is 20% @ 12Hz. 12Hz is
generally considered to be below the temporal limit of perception.
Therefore, the combing can be uncompensated.
My actual testing confirms this.
