Comment (by starlight):

 The concern of this ticket is with regard to the observed value published
 by the daemon rather than the Torflow calculated vote resulting from it.
 I suspect that changes to measurement logic in the daemon have likely
 reduced or eliminated the error last definitively observed in 2.6.10.  I
 may yet write a monitor to evaluate the quality of daemon measurements.

 Torflow adjusts self-report with the ratio of the measured bandwidth for a
 relay to the average of all measured bandwidths in a manner short on
 nuance.  Wrote about possible ways to address that here:

 Have considered opening a Trac ticket encompassing the ideas, but am
 waiting for an opportune moment at a point where serious comparison work
 is evident.
