Afternoon, Garrett. Wow, I've not noticed the E/T thing. I'll watch it on the way home tonight.

As far as instant, you mention you re-set it from a standstill. You're probably getting 3 mpg for the first 10 miles per hour increase and then may 10-20 mpg getting to cruising speed. You have to overcome that, so your instant would not be the same as your trip.

My Navi/trip computer uses GPS for mileage, as opposed to tire rotation for trip. In my testing, I've found the Navi to be more accurate. Among others, tire wear and amount of turns and curves can affect tire rotation. My Navi/trip adds up miles *slightly* faster giving it a *slightly* higher mpg.

I'll let you know about the E/T.
