Default ET and MPH with Top Up vs Down

Has anyone done a back to back comparison of ET and MPH with the Top Up vs Down?

I seriously doubt there'd be a significant difference, certainly smaller than repeatability from run-to-run. No weight difference and the aerodynamic difference on a 12-13 sec car would be insiginificant. Even on your nearly 900HP machine, aero difference in drag would be like a bug in the windshield.
