 Replying to [comment:10 arma]:
 > A) We should get gsathya or asn or whoever to confirm that dropping
 relays with bandwidth less than X doesn't change any of the diversity
 metrics much (because they're never picked often enough to matter).

 So, is this ticket about dropping relays from the consensus, or taking
 away their Fast flag?  I can see how we can graph the former, but I'm not
 sure about the latter.

 > What's the largest X for which you can reasonably say that?

 Sounds like we want #6232 graphs with the minimum bandwidth to keep relays
 in the consensus on the X axis.  For example, a graph similar to
 https://trac.torproject.org/projects/tor/attachment/ticket/6232/entropy-
 august.png would have its blue lines decreasing steadily, because we're
 taking away relays, but the red lines would stay on the same level and
 only drop in the last third or so, because we start taking away relays
 from the slowest ones.

 Is that what you have in mind here?

 gsathya, asn, is this something you want to look into?
