> > 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.

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.
