And tire temps
Unfortuneately I have run into this before, I thought my car plateau'd after about 30min from a previous test. Also why I started with multiple runs without changing the test, thought I was golden after runs 3,4 came in with the same result, but that faded when I ran #6. At this point, I'm guessing my mileage could keep climbing at an incredibly slow pace for as long as I could take sitting in it for a day. Maybe I'd hit the ceiling faster if it was 105f day, but then I'd want to run the a/c anyway.
