Comment:

 So I'm not sure exactly ewhat this is asking for, or how to implement it.
 But as far as bwauth debugging information, what I have wanted/envisioned
 are the following:

 1. A graph on Atlas, per-relay, that shows each bwauth's votes for that
 relay over time
 2. Something (maybe a graph) on Atlas, per-relay, that shows which scanner
 the bwauth made the measurement on
 3. A series of graphs that shows below/median/above bwauth buckets for
 relays where each graph only applies to one country's relays.
 4. A graph or series of graphs that shows bwauth variance on relays per-
 country.


 (1) is for relay operators to understand why their bandwidth usage may
 have changed without requiring them to do some ugly consensus/vote
 grepping. But it requires changes to OnionOO and Atlas.

 (2) is also for relay operators, but also bwauth operators, to confirm
 that sometimes relays slip between scanner cracks. To perform the analysis
 at all, bwauth's need to apply this patch:
 https://gitweb.torproject.org/torflow.git/commit/?id=7e4ef735858acf5d2fbb183b6f8418b7fc2b364a
 To get it into Atlas, we need the data in OnionOO, and to get the data
 into OnionOO we need it in Collector, (#21378) and to get it into
 Collector we need it exposed by the bwauths (#21377).

 (3) Should confirm (or reject) the hypothesis that some bwauths make more
 high or low measurements because their geographic location hurts or helps
 them measure a disproportionate amount of the network.

 (4) Should confirm (or reject) the hypothesis that maybe, just maybe, our
 bwauths tend to agree with similarly-located bwauths for similarly-located
 relays.


 I'm not sure if any of those is what you said though.
