I am coming from a 90D so I am trying to understand he difference in range with the P a little better. Basic question is does the wh/mi work out the same between the two? In other words, let's say 290 wh/mi in my 90D got me 300 miles. If I achieve 290 wh/mi in the P, can I expect the same 300 miles, or less? My assumption is the answer is yes and the 290 wh/mi is just simply harder to achieve in the P (such that driving in the same manner in the 90D would have been say 280 wh/mi instead of the 290 shown in the P). Sorry if this is as dumb of a question as I think it is.
