 > > Also, the way the bandwidth authorites work is to group nodes with
 similar values for the ratio (consensus_bw / descriptor_bw) for
 measurement together in 2 hop paths. So if we set this to like 50 for
 unmeasured nodes, they will currently get grouped with the slowest
 measured nodes on the network. That might be a hard sinkhole to get out
 of.

 bandwidth (in which case this 50 doesn't matter), or the future case where
 you're hoping to feed back the consensus weight into the new weight?

 Present case. Even without feedback, the pairings of nodes during
 measurement is decided based on the ratio of consensus to descriptor
 bandwidth... So the 50 will matter now, until we find an alternate way to
 handle it for grouping.
