Obviously this plan is riddled with control problems especially considering the wacky weather that is February and March in the mid-Atlantic. On a warmer day I might try the back to back testing and just have to ignor the idea of computer needing a reset. Plus, I thought I lived in one of the flattest states in the Union until I started paying attention to MPG and learned that Delaware sure isn't the pancake I thought it was...even if most of these hills are man-made overpasses lol. Either way I still haven't found a flat road without traffic lights in an area capable of 50+ MPH.
