Yeah, good point (the examples, not necessarily any jargon-ful explanation of them). Sound waves, or even better, slow-moving vortices, or also better and different, diffusion of a cloud of one gas through a room filled with a different gas, show that you don’t get total mixing of a room on one-second timescale.
I think most likely, I’ve mangled something in the process of extrapolating a paper on a tiny toy model of a few hundred gas atoms to the meter scale.
