I don't have pictures of mine, but i calculated in a manner which you did. Today is Sunday and I am planning for a hypermile, my kids are quite excited, lets see what it does with an A/C on and during a day (above 40 Degree Centrigrade) in which A/C is not going to trip in a frequent manner. Expected load in the car will be 2 adults and 2 adolescents. Fsd to Kallar Kahar and then I'll be back I will post you wit the result in night or tomorrow. It would be an extreme conditions test (Summer dopaher with A/C on).
