Yeah, I was busy getting more video this weekend...
Quick results... I have only entered the "A-B non-tail mods package" test so far (grille block, passenger mirror delete, driver's mirror folded, wheel discs, rear skirts, rear smooth undertray, rear wiper delete), and it showed +7.5% @ 65 mph / 105 km/h. The tail A-B-A numbers showed an additional ~10% @ the same speed, but that number is from a quick calculation. I haven't actually stuck the run results in the spreadsheet yet.
So this message may self-destruct when I post the full, double-checked results.
