I don't think that the numbers you throw in here carry a lot of meaning.
As a musician, I certainly have to be able to produce and recognize runs
with individual notes shorter than 0.17 seconds.
The speed typing record is at 216 words per minute. That's words, not
letters.
So whether or not those kinds of delay turn out relevant in practice
very much depends on which tasks with what kind of interactivity they
appear in. Blanket musings about some "speed of thought" are
meaningless.
