Dan,
Enjoy the car and do not spend too much time worrying about small things like not being accurate below 20 mph. Hell, the car does not want to be running below 20 anyhow and how long are you there, a second? :roll eyes: Enjoy and don't let Patrick get you down. He's just jealous that your car looks so nice and isn't a funny shade of "What did the dog leave on the carpet now?"
