Thanks guys, but TimK got the gist of what I was trying to ask.

I just added the extra thing about multiple acceleration because I notice the rather large energy flow from the engine to the battery when you fake shfit, therefore it seems you get a lot of that acceleration energy back to your battery.

The multiple fake shift is like dring a stick shift, which seems more efficient.

TimK's numbers are made up, but if its close that's 10%. Do that many times during the course of the drive per day, and it adds up.
