Missing rows in the tables are human reaction time (~250 ms) and human perceived-as-instantaneous time (~100ms).
Beyond a lot of wasteful programming, we also understand better today what we are engineering for than we did in 1977.

It is a long-haired black cat. It doesn't like us. But it does like taking a shortcut through our front yard. If it sees us, it freezes. It waits, mid-stride. Then when it's satisfied we're not a threat, it starts moving again. If I move my arm or shift my body, it freezes again, sizing me up, sure that this is the day -- after all these years -- that I'm finally going in for the kill.
What's weird is I am convinced that this cat knows when I'm going to start moving. It halts before I move. By the time my head is moving or my arm is waving, it is already frozen and on high alert.
My working theory is not that this cat is telepathic or that it has defocused temporal perception. Rather, I think that because the cat is smaller than I am, its eyes are closer to its brain, its nerve impulses don't have to travel as far, and it really and truly knows before I do that I'm moving. Otherwise I can't explain this cat's superhuman reflexes or its blatant disregard of general relativity.
When your eyes focus on something new, your brain deletes the blur from your memory and fills it in with what you start looking at. The cat could notice and stop during your refocus, and because you can't see it during that period, all you see is it already stopped and perceive it as having been stopped the whole time.
Nonsense. You can test this yourself. Open a fast terminal, eg. xterm (libvte based terminals have a low framerate and are unsuitable).
Try:
sleep 0; echo "test"
sleep 0.05; echo "test"
This test shows your visual system can detect the difference of 50ms between animations. Indeed, the human visual system can also tell the difference between 60 FPS (16ms) and 120 FPS (8ms), and even higher! This doesn’t mean that you can tell the difference striking a key and seeing the character draw on the screen after 8ms instead of 16ms.
> 0.1 second: Limit for users feeling that they are directly manipulating objects in the UI. For example, this is the limit from the time the user selects a column in a table until that column should highlight or otherwise give feedback that it's selected. Ideally, this would also be the response time for sorting the column — if so, users would feel that they are sorting the table. (As opposed to feeling that they are ordering the computer to do the sorting for them.)
