like a non-negligible fraction. Could they come form things like
https://www.torproject.org/dist/torbrowser/update_2/hardened/Linux_x86_64-gcc3/6.0a4-hardened/ALL
which are the update checks I talked about above (and which should get an
update.xml file back as an answer)?

I think you are right here. One admittedly far-fetched scenario I had in
mind while writing my last comment was our incremental .mar file update
failing badly which could lead up to 2 .mar file requests (one for the
incremental one and one for the full one) per one update ping. But that
would imply a weird usage pattern of almost all of our users. So, yes,
these requests are something else.
