Comment (by pastly):

 This seems to be all about bandwidth self tests (see
 `router_perform_bandwidth_test` in src/or/router.c for where the self test
 is performed).

 Regarding sbws: it currently uses consensus weights (unfortunately) and
 will soon use relays' RelayBandwidthRate/MaxAdvertisedBandwidth (AKA:
 whatever ends up as the first number on the bandwidth line in server
 descriptors). It doesn't care about self test results.
