My laptop shows a slight difference. It's a consistent 32 in the first unconstrained loop test, and it fluctuates between 31 and 30 in the _limit 30 test.
On the movie question, 35mm film movies are indeed 24 frames per second, but each frame is projected twice, to prevent flicker. And too, motion portrayal can be very bad in some cases, so cameramen use all manner of tricks to make it look right. In live sports, TV uses 60 frames per second, even though TV gets by with 30 frames per second for normal material.

"Have you ever watched live sports on a streaming service such as Sling TV and thought it didn’t look quite right? Compared to cable, satellite, or over-the-air broadcast TV, streamed sporting events can look a bit choppy or jittery, making it harder to keep track of quick passes and fast breaks.
"The issue here is frame rate. Sports telecasts typically come in at a smooth 60 frames per second. But that higher frame rate isn’t a given with streaming services, where that same video might play at a choppier 30 frames per second. As this 60 fps vs. 30 fps comparison video on YouTube illustrates, frame rate is the difference between a lifelike picture and one that looks more like a scripted TV show."
I too would expect therefore that mice should be polled more like 60 Hz.
All sorts of interesting stuff on this subject.
