Very good! Aside from all the "criticisms" you're gonna get, you proved several things: 1) Wind helps / hurts MPG!
2) Your observation of wind speed (5-7 MPH) gives an average value of 6 MPH ; The total delta is ~12 MPH.
3) Don't forget these values are for your Civic only! Other shapes will act differently (ignoring such parameters as differences in weight, frontal area, accessories, wax jobs (LOL), etc.).
4) The choice of a writing utinsel beats a stick in the dirt every time! LOL

In my xB on my trip to Maine I was cruzing at 70-75mph behind a few big vehicles and was getting 40-42mpg then lost them and it dropped to about 32mpg. This box is definately not like my Geo.

You found out a truth! Drafting can be fun! Also dangerous! A rock kicked up by the rear tires on these big rigs (most mudflaps are too short!) will find your windshield / paint job / headlight! Bang! Then, think of all the gas you saved!
