I did the same thing, naming my Trip B to "Lifetime". Over 400 miles I am averaging 245whr/mi. Not bad considering I have 19's and a mostly highway commute of 22 miles (although the highway traffic is stop and go for half the commute)
This morning there was really bad traffic on an interchange overpass, so TACC was creeping slowly uphill. Think it topped out at 489 wh/mi since the morning charge, haha. By the time I was at work it was down to a nice 249 wh/mi.
