The routes you discribe are similar to two routes I travel on a daily basis, except for elevation changes and the amount of stops. In most all cases, I start with a minimal SoC and at the end may very with the same or a little higher SoC. Given the amount of a ~20% longer distance with one more stop, I would go with the shorter route.

However, there is no way I could get those results accelerating (the pulse) up to 42mph and having to stop 4 times, and I always glide in neutral down to 25mph if traffic permits. My best mileage with P&G is a 25mph target low speed and a 35mph target high speed. Of course when I have to drive faster, I do take my FEH to 42-43mph for P&G, but my mileage drops off considerably accelerating to that target speed. With the thin air and hills, I still can't see how you got those numbers stopping 4 or 5 times, even if they were rolling stops. Don't know how dropping 50 feet in elevation would add to my numbers though.

My FEH gets bad mileage with the small generator charging a low SoC from a restart after an EV glide and run. I use a fake shift in "L" at 30mph (not always though) and again at my target speed (35-43mph) to go EV and glide switching to neutral as the tach bounces.

Most of the other hybrid model hypermilers can't use P&G effectively like we can with the FEH with a drained battery. It would be interesting to compare how there Hondas and Toyotas would compare on your routes.

Comparing my best 20.3 mile round trip to your best 20.2 round trip, I got 70.3mpg and you put 68.3mpg on your sig page. It would seem I would do a little better than your numbers here also. I don't know where your SoC was when you started your 20 RT, but mine was on its last leg when I started and finished.
