So, no flights to POL from AND?

Reply to comment by Piffdolla1337take2 in TIL, canines have a more sensitive CFF of up to 80Hz or 80 flickers per second. "This might explain why most dogs cannot be planted in front of the television to engage them, it doesn't look real." by chandu6234
No, flickers. Flicker fusion is about whether you perceive a pulsed light as a constant brightness or as a series of individual flashes. That is not the same as frame rate - for example, on traditional film reel projections in cinema, each frame would be flashed three times to give 72 Hz of flicker with 24 fps, because flicker fusion for humans is in the range of several dozen hertz - hard to pinpoint an exact value, since it depends on a whole damn lot of factors, but light flashing at 24 Hz is pretty much intolerable.
Its relation with the ability to perceive fluid motion is also rather distant. Sure, both deal with the time resolution of the eye-brain system, but fluid motion starts somewhere between 10 and 20 frames per second and continues getting smoother well above 100 fps, though obviously with strongly diminishing returns at that point.

Depends on the industry. American tools? Probably in line with the finest stuff from Europe or Japan. American cars? No thanks.
