Yes, I believe you are correct in your analysis of my driving. However, I try to end the 60 mile trips with no EV remaining most of the time. Would it be better to burn the EV miles going uphill? It seems to me better to burn them going downhill so the ICE is off for a longer period of time. My overall calculated MPG after 5,000 miles is 80, but since that includes lots of short all EV trips and some long trips only on EV, it doesn't tell the entire story of my 60 mile trips. A recent 200 mile trip starting with a full charge and not charging again resulted in the vehicle telling me I got 68 MPG which seemed very good to me. My 2004 would probably have been in the low 50's for such a trip.
