I use a lot of "deadband" coasting for my glide, and will in fact leave it in L for the whole trip once everything is hot and ready for EV. If you are beating me ( and probably are ) it certainly is not by 38%.
Thinner air probably means I get the same at 40 miles per hour you get at 35. Just a rough guess. P&G 35 to 25 seems just too slow for me!

Never said I was beating you by 38%, I would have to be near some of better Insight drivers MPG for that. Your using the confusion card with that statement. The 38% number came from my coasting test down from 40mph in "D" (drive) and coasting down in neutral to a stop. The distance was 38% further in "N" after many test on a flat road. I never compared dandband coasting to Neutral coasting at all if that is what you are referring too. The axles are disconnected from the output shaft in neutral with no regen possible. With deadband coasting, the axles remain connected and small amounts of regen is possible that may not show up on the energy screen. In my steady state speed test, I found a big reduction in MPG at speeds below 50mph when I used "L" for the test over "D". The increase in regen in "L" was the reason for the decrease in MPG. It's no big deal during acceleration, but I would have concerns myself during a deadband glide in "L".
As far as the difference between 35mph and 42mph, it has more to do with the length of time the ICE is on. From 25mph to 35mph compared to 28mph to 42 miles per hour, I'm only decreasing the time it takes me to accelerate 10mph, while we both do by increasing the time to accelerate 14mph if I take it to 42mph like your P&G. That, and wind resistance (higher speeds kill MPG) in our FEH (brick) play a big roll IMO and numbers.
Also, I find your SG average speed reading of 30mph very high with 4 or 5 stops.
