Sounds a bit low. I've never seen mine drop into the 10's. Your reserve amps might be on the low side. How old are these batts? Not the originals, I hope. Right here is where your FICM is most vulnerable, with glow plugs on, voltage low, and you hit the starter. I would get those batts load tested.

Your alternator is working good.
