Your BD was low, and might have resulted in some residual salt in the first water after regen.
Don't blame the installer for the lean settings. CA wants it that way. I am not a pro, so I am suggesting more luxurious (less Spartan) settings.
Your Backwash minutes were fine.
Note the numbers below are not quite a match for a 16 minute

The less salt per cubic ft, the more salt efficient, but more hardness breakthrough.
