Yep, that sounds reasonable to me.  fwiw, apt_preferences(5) indicates
what the different cutoffs for priorities are, and explains why
jessie-backports defaults to something in the 200 range ("NotAutomatic:
yes" and "ButAutomaticUpgrades: yes"), and 150 should still have the
same properties (it's above 100, but below 500).
