Hi all, Please let me know if I am doing this math correctly. I am taking a road trip soon, with 6 people and a roof box. My testing is that my energy usage is 375Wh/mi at highway speeds with the box on and A/C running pretty good. To be safe, I'm going to assume 400Wh/mi. What is the most accurate way to convert that to rated miles? In other words, if I assume I travel 100mi at 400Wh/mi, how many rated miles should that take up? My understanding is that rated miles assumes 308Wh/mi, but I've also heard 300Wh/mi and 29x Wh/mi. Thus, I'm assuming I will need 100 x 400/308 = 130 rated miles. Key question is: what number to use? 300? 308? something else? Thanks!
