Well… when the job ran overnight,
my user with 6 bronzes got 1 silver 
my user with 13 bronzes got… 1 silver 
This part in the tutorial made me think a separate, explicit backfill job wasn’t necessary
Since daily a full backfill runs regardless you must take that into consideration and include handling of the
:backfillparameter.
For users who’ve already earned more than 1 silver, how do I get those awarded? Do I have to do that manually?
