Comment (by gk):

 Replying to [comment:3 karsten]:
 > Sure, we can include number of requests.  But does a single Tor Browser
 instance only make exactly 1 request to update to a new version, or does
 it make several of those?  That might make it difficult to compare the
 numbers.

 It checks periodically whether there is a new update available. But once
 it determines there is indeed one out there then it should fetch just one
 .mar file in the vast majority of cases. That's why I was explicitly
 asking for the requests responsible for the downloads, e.g. those
 requesting the .mar files.

 Do we understand the nature of the other requests? 38% sounds quite 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)?
