11.70-11.84 based on my .01 to .02 per 100'.

Brian comparing cars and planes and through a 1/4 mile where the DA likely would be the same from start to finish. How many times would the DA change on a flight? Probably many times depending on distance. Also how many planes are supercharged, and how are they affected by DA compared to N/A planes. Run your car at the track first, then run it in different DA's then compare it to planes. Look forward to your actual experience findings from running your car, not your plane.
