CarWings only has a month and annual by calendar year option so for the consumption values I just added the August – December 31 with the January to date numbers but for the efficiency I think I would have to provide a weighted measure to each number before combining. My abilities extend only so far as to know that I just can’t average the two since this is a measure of electricity used to miles traveled.
If some one out there would like to figure it out: For 2012 I consumed 1211 kWh and traveled 4369.2 miles (3.6 miles per kWh). For January to date I consumed 148.9 kWh and traveled 426.7 miles (2.9 miles per kWh).
