What you describe is plausible. If you want to get more confidence, you
could rm -rf ~/.tor/cached-* so your Tor client has to fetch everything
The "we now have enough" line shows up once Tor has at least 1/4 of
the descriptors (or in this case microdescriptors) that it knows it
wants. So it makes sense that it takes a while after that point to a)
fetch the rest of them, and b) build a circuit.
Note that the main benefit you'll see from microdescriptors is in reduced
directory overhead *after* initial bootstrap -- because microdescriptors
don't change as often as normal descriptors so you can keep them cached
for a week. They don't help so much with the initial bootstrapping cost.
