smallify Quick checks

Browse source 
Quick checks aren't super helpful, but they can test random stuff
a bit, so let's keep them, but make them smaller. Also, let's cram
the random selections into the first quarter of a shard so we see
more container updates to fewer containers because that's probably
more interesting.
