I thought something was wrong with my car also until I read up on it.
That's not erratic behavior, you are probably just used to older charging systems where the alternator's output is always full blast and a voltage regulator controls it down to about a constant 14V. Your car has a smart charging system that adjusts the voltage depending on demand, that's why you'll see it down below 13V sometimes. I think it's supposed to prevent battery overcharging and save fuel.
