Data from MIR in an August when I had the Challenger there shows a calculated density altitude of 3,913.501 ft. And, yes, the car was off about .3 and 3 MPH from what it would run in the fall weather a few months later
Even the close-to-sea-level tracks in the Mid-Atlantic take a hit w/ the summer heat & high humidity; it ain't always mineshaft air quality here, either. It could have easily been 5+ degrees hotter and closer to 100% humidity, which would have jacked the DA up even more.
