Would you mind changing all of these to the word "microseconds"
instead?  "µs" was already a cryptic abbreviation, but at least it was
an official SI cryptic abbreviation that people could look up easily.
"us" is not easy to look up, because there are lots of other meanings
that are much more common (see e.g.
https://en.wikipedia.org/wiki/US_(disambiguation) -- microseconds are
mentioned but only at the very bottom of the page).

Otherwise, LGTM.
