...at least for a fairly short trip. Trip was 12.6 miles and the computer indicated 49.4 MPG. A few minutes earlier it was up around 51, but...pictures or it didn't happen.
The entire round trip was 26.3 miles, and the average for the whole trip was 47.1 MPG.
I'm starting to doubt my ability to properly exploit BSFC, because I achieved the 49.4 only using granny techniques. On the (slightly longer) return trip I averaged 45.0 while trying to use BSFC. There's only a ~30 foot elevation difference between the endpoints, so that shouldn't matter much.
