Passers-by glance mid-spot and look away after two or three seconds. Brand and offer belong in the first half and then stay put.
Rule of thumb: one cut per two seconds. Nobody reads more from twenty metres.
How often your creative runs on one screen.

Slot divided by loop.
Rules of thumb from practice, not a measuring instrument. The only real check is the spot on the screen.
