Comment (by teor):

 Replying to [comment:7 starlight]:
 > thank you for the update, bwscanner I presume?

 No, simple bandwidth scanner.
 bwscanner doesn't generate files that authorities can use yet, so I don't
 know if it will use self-reported bandwidths for scanning.

 > I won't spend time quantifying this issue with 0.3.3, at least for now,
 though I did come up with a plan.  If peerflow happens then measurement
 quality is a concern; could spend some time on the aforementioned
 analysis.

 I think there are some inaccuracies we will just have to live with, and
 this might be one of them.
