When a car goes up / down hills or around a curve, the oil sloshes so your perfect level is now not so perfect.
Most engines will run on 2 QT in the pan, however long term it is better to have more oil so it has a chance to deaerate / not slosh away from the pickup.

Very good point, I was surprised to see no baffles in the pan when I had the one off on my engine as it was out and on the stand. That's the same one I had a bugger of a time getting the new seal to actually seal.
My practice has always been to check the oil in the garage first thing in the morning once a week if it's a daily driver, the floor is about as flat as I have found, even though technically it has a slight fall to allow water to drain out the front door incase you ever wanted to hose it out (most do) mine has an 1/16" fall per foot, so around 2" for the entire length of the garage.
On a long trip, I'll check it at every fill up, just fill, to inside and pay or pee, and by then it's settled enough to check.
