Highest MPG at which pulse and glide range?

Here are my mpgs on my 2012 Toyota Prius (not a plug-in or Prime):

~10,000 miles, 73.5 mpg.


924 miles, 77.7 mpg (on one full tank of gas).


Is there any way to improve the mpg without draining HV battery? Is there a P & G range that is most optimum?

Currently, I accelerate to 40 mph at mid-line here (No EV light):


Then pulse to 45 mph here:


Then glide to 37 mph (if no one is behind me) or 33 mph (if no one is even on the road) here:


If someone is behind me, to maintain speed I will lessen gas throttle to midline or (with a decent tailwind) to here (No EV light):


The above P & G procedure is for all speeds except for the following:

At lower speeds, accelerate to midline first, then immediately pulse to 5 mph above speed limit here (No EV light):


Then gliding to 3 (or 7) below speed limit here:


At entrance ramps to freeways, I accelerate to 45 mph here:


Then to 50 mph here:


Then to 54 mph here:


getting 62 mpg (+ or - wind speed).

At 3/8 mile before exit ramps, I will gradually slow down to 45 mph here (No EV light):


Then at the exit ramp, glide or coast (depending on traffic or length of ramp).

If headwinds are greater than 5 mph, I use a slower parallel road.

I do not use Neutral.

I do not drive from a cold start until the engine turns itself off.

I always drive in the right lane.

I do not use the A/C unless above 88°F or high humidity.

I do not use the heater in winter until engine is warmed up.

I do not turn off (power down) the Prius unless I know for sure I will not be driving again within 5 minutes (maximum 10 minutes).

I keep tires inflated to 38 psi.

If anyone has any advice to improve the above steps, I would greatly appreciate it.

 

Also, from a dead stop, I only use EV up to 12 mph, then immediately to midline.

 

Sorry for the apparent deception. I was using Google Photos' editing tools to overlay white shadings, red arrows, and the blue "eco" letters to represent how I actually drive, since I thought it would be harder to take an exact and stable photo while driving.

 

I just took these pictures today, though it's dangerous to do while driving (but at least it was daytime, so I can see everyone everywhere at all times).



This is the borderline area without EV light.



and with EV light.



And this one is how I do minimum battery power while gliding.

And these have even better gas mileage than those posted above.

I am so disappointed in your lack of faith that these high mpgs are possible on a long term basis.

 

Finished today with 79.2 mpg driving 420.5 miles using 5.31 gallons of gas.
