Comment (by starlight):

 According to the vote document it's "software_version=1.1.0", what I say
 above in the description (which you copy in reply), is the current git
 release and you posted about it on tor-relays.  This ticket is under SBWS
 so what doubt inspires the scanner/version question?

 The out-of-whack numbers I observed reverted--SBWS requires a substantial
 ramp-up time before quality is achieved.  Torflow has an explicit
 mechanism to delay publishing until equilibrium is present, suggest that
 SBWS employ something similar.

 My recommendation is to examine raw votes in comparison to the POC scanner
 Matt authored as a QA validation.  I still like the idea, even with the
 vote quality improvement.
