Comment(by arma):

 Replying to [comment:26 mikeperry]:
 > 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.

 Oh. So both my patch and Nick's patch will make this a problem for you.

 Can we make it so the bwauth ignores the consensus weight (i.e. calls the
 ratio 1) for relays that it has no local opinion about yet? That won't be
 perfect, since a given bwauth could form an opinion even though the other
 bwauths are voting 50, and then that bwauth will believe the consensus
 weight next time.

 My patch makes moria1 vote Capped=1 on the w line when it capped. But that
 doesn't make it into the consensus. But it could if we wanted to make a
 new consensus method.
