I have figured out some things I'm not doing correctly (without even doing detailed tests, yet).

I think my "pulses" are both too aggressive and not taken high enough over the posted speed limit, so I spend 2/3 of my time pulsing and 1/3 gliding. That's probably not helping. Combined with the simple fact the HiHy is a bigger vehicle and cannot "glide" as far, P&G needs to be done much more carefully, if at all (see next paragraph).

My best MPG (34.1) made much heavier use of the traction battery than "P&G" does. Obviously, draining the TB means it has to be recharged, and while the ICE can do that, it defeats the point.

As a result, I will be testing the "Prius Method" but I doubt it will work best for the HiHy. So long as the TB isn't drained heavily and recharged by the ICE, I believe HiHy gets the best mileage when more electric power is used, but is regenerated. So, it looks more like "pulse, electric speed maintain, regenerate."

On the highway, I'm guessing P&G is my best bet though, because over 40MPH the engine insists on running.
