Once you get the vents set correctly, and the flows balanced, then it can be left alone.

Or maybe I personally just have a very consistent sense of what temperature I want the car to be, I'm not sure. I do know that while I like 19, my wife likes 21 on the passenger side, and the car seems to be able to deal with that just fine.
