Perhaps a third battery charge display option is needed

This is still not true. It is not using past consumption from before you started the Nav route, but it is updating based on the current consumption. As you say, you can prove this to yourself by doing this: while you are navigating and driving, turn the heat on HI. Within a couple of minutes, you will see the energy display show your remaining % at arrival start falling very rapidly. It is recalculating with your new much higher present energy consumption projected out over the rest of the drive.

I have not seen that before, but I will try it on my next road trip and see what happens.

IMO they should just get rid of the "Ideal" miles, and always show both % / kw and miles / mph on all screens, all the time.
