Sounds like your speed limit is 70 or more to do to do 72 miles in 65 minutes, close to a 70 average?
40 should be doable with a 31 highway rating but you need to find or create opportunities to coast, even if you pulse to 5 over on a deserted road and coast down any grade that extends your coast.
If thta commute is all you drive the car then 28 is not even epa highway. Local driving also?

I had a rig in front of me this morning and stayed behind him for about 50 miles. Distance between me and him varied depending on what I was doing. Probably within 3 stripes at times, but generally a bit further back. Not too close to be dangerous, but probably not close enough to be very helpful.
The Accord doesn't seem to have any trouble shifting between a gear and neutral. I do either DFCO or coast in neutral depending on length and grade of hill and what else is going on around me. DFCO on the accord is pretty good, if it kicks off due to low RPMs, and I still have some downgrade left, I shift to neutral to keep the coast going.
I have mostly gentle rolling hills so I'm still learning how best to deal with them all. I've been driving with load going up, then pulsing near the top to get up to about 70MPH, then DFCO or coast in neutral down. I find that I'm still gaining a little MPH even at the very end of the commute.
I have mostly 70 MPH limits, but some 60s and one town with 4 lights midway through the commute. Prior to doing hypermiling, I was doing 75-80 MPH for large stretches of this commute which allowed for close to 60MPH average speeds. With hypermiling, I'm staying around 60MPH with 65-70 on pulses.
Probably about 80% commute/highway (maybe more) and the rest around town.
