Another MPG Boosting Technique or Not?

Today, while I was driving on the freeway, I noticed something as I was driving.



So if I stay steady at about 80% of the bar, between the red lines, I get a 45 mpg reading at about 75 mph. Note I am not pulsing or gliding here. I am only maintaining steady speed.

If I slide the bar down to about 60%, so that I am between the white midline and the left red line, the instantaneous MPGs actually go up to 80 mpg. Note I'm going about 70 mph at this point.

Seems I can use the throttle to move the bar anywhere from 60% to about 85% without changing my speed that much. But the MPGs vary a lot. From about 80 mpg at 60% to 40 mpg at 99%.

So I keep modulating between 60% to 80~90% and my avg MPGs seem to be going up, and battery is not going down much. Can I call this slow-pulse / fast-pulse? Well you don't slow down much in the slow-pulse and the fast-pulse is easy because you never slowed down that much in the first place.

Perhaps I am draining the battery a bit and then charging it up just as quickly, and this actually is overall more fuel efficient? Like a mini-drain and mini-charge. Could this be majorly stressful for the battery? I really don't know if this is even the case.

It's hard for me to switch to the other view to check the arrows and simultaneously be sure that I have the bar at 60%. I don't know what mode the HSD is doing (Battery-Draining, Battery-Charging, Series-Parallel, etc.).

 

Actually I haven't. It's not in that Max MPG video. That video says to never stay above the midline.

Edit ... sorry I take that back. I'm gonna watch that video again, report back soon

 

Ok you know I've watched that video again and even though it mentions Super Highway Mode in the beginning, it never mentions it again. It doesn't say what it is, or explain how to do it.

It does say not to keep the bar above the midline. So I've been avoiding that area just above the midline. This is probably why didn't notice this before.

What I described is switching back and forth between these positions and it boosts MPGs. Unlike P&G, it doesn't piss off the guy behind you that much. Is this Super Highway Mode?

But anyways, I'm not sure what Super Highway mode is, I'm researching it, and I don't know if what I described above is Super Highway mode. But if anyone cares to let me know, I'd appreciate it.
