 I downloaded your sbws datadir and wrote a little script to print how
 often a relay has a list of saved `relay_average_bandwidth` containing
 more than one unique element.

 It found that 1868/7999 relays had `relay_average_bandwidth` values that
 weren't all the same (118/7326 if you only look at success results). I'm
 guessing relays don't update this value in their descriptors very often.
