I say you are correct. I'm sure the engineers are well aware that neither the dipstick nor the manual service fill capacity is "exact." Between different sized filters, draining time, not being level when measuring, being careless with a dipstick, a dipstick being hard to read, and so forth, there's plenty of room for inaccuracy.
What's "right on the dot" here and now may not be the same ten minutes from now. With the G37, I always check it after it's been sitting all night in the same place in the garage to minimize those little issues. That being said, the taxis were always checked after being off for no more than 5 minutes after running all day. You make due with what you have.
Listen to Trav - a few ounces over or under are immaterial. If he worried about that, he'd never get anything else done in his life.
And yes, overfilling is not a good idea.
