Using the calculation, my last charge got me 163.4 eMPG. (226 wh/mile)
One thing I have noticed is that with longer trips, my wh/mile improves. If I only go a mile or so, then recharge, my wh/mile value is just above 300. On 10 mile trips, the value is normally around 260 or so.
This particular charge was exceptionally low, but perhaps I wasn't driving as fast... (fast is a relative term in a Citicar...)
