Twin Falls to Declo, ID on a full battery charge.

Today, we went from our home here in TF to Declo and decorated our family graves.
We started out with a full battery charge, 37 miles anticipated battery range.
We drove the old Highway 30, with the cruise set at 55 MPH, or the speed limit.
I made the whole trip with the Range selector set in LOW, to maximize the regeneration when coasting and braking.
I started the trip, in the Normal Mode, and drove in this Mode until the Battery Range Meter said that I had 12 miles remaining.
At this point I switched to Mountain Mode, the engine is now running powering the car AND recharging the HV battery.
I continued driving at 55 MPH with cruise control on for about 10 minutes in Mountain Mode.
I have found that the Mountain Mode typically builds the HV battery back up at 2 miles for every 5 minutes of driving.  This recharging rate of the battery is not set in stone because of radiations in road elevation.

I now switched back to the Normal Mode and observed that the HV battery had been recharged to an anticipated range of 13 Miles.  I now drove in the Normal Mode until the HV battery was again down to 10 Miles remaining, where upon I switched back to Mountain Mode.

I did this several times in the 45 minute drive and I did not make my switch into the Normal Mode if I was driving up a hill or on a stretch of road that had a visible elevation increase.
I am not sure if this holds true if the elevation is dropping, if it is better to stay in Mountain or to go back into Normal.  I don't know precisely which Mode, MM or NM will give me the most regeneration.
At this time I feel that going down hill in MM gives the best HV battery recharge for the same period of time.
But, I need to try this several more times to be sure.

Okay, here are today"s results.
I arrived home with 1 Mile remaining on the HV battery, which is what I wanted to do.
I wanted to use up (as much as possible, with out the gas engine coming on this last time) all of the HV battery charge as possible before I arrived home.
Nice! We squeaked in with 1 Mile remaining on the HV battery.
The 239.4 Miles on the trip odometer includes the miles from our fuel fillup in Snowville, UT on our way home.
The main point of this display is to show that we arrived home today with 1 mile remaining.
This display is showing the information on this HV battery charge.
We have driven 127.1 Miles on this charge, 83.6 on the Hv battery and 43.5 Miles on gasoline.
We used 10kWh of electricity or $1 ($.10/kWh) and we used 1.78 gallons of gas.
The display says that we achieved 71.0 MPG!
This gets complicated, to me anyway, because we are using gas to drive the car and recharge the battery that  both get you down the road.
But, this looks pretty impressive!
