Filled up the gas tank, and the average is 26.3 MPG. It seems to be staying pretty consistent now, which is nice. I'm going on a 330 mile round-trip drive today, so that'll use up a tank.

I also thought that if the kamm was too short (such as simply detaching airflow off of the roofline), then it would just make it seem like the rear end was larger and produce a larger wake, since the airflow does reattach to the trunk right now. I guess I wasn't thinking about the flow around and above the vehicle as well.
