Comment (by teor):

 Our acceptance criteria for sbws is a 50% variance from the consensus,
 because that's what torflow's variance was before we started deploying
 sbws. See #27339.

 Replying to [comment:9 starlight]:
 > Defect is extremely severe.  SBWS should be removed from production
 until this is fixed.

 This defect has a limited impact. So we won't remove sbws from production.

 > Longclaw has thirteen percent of listed relays with incorrect descriptor
 information more than 7% away from the published consensus.

 Why pick 7%?

 The total consensus weight of the bandwidth authorities now varies by up
 to +43%, -14% from the consensus.
