I do see your point, and I think offering all three solutions (manual, GPS, OBD) would be the optimal way to go about it. I have never programmed with GPS before, but from what I have read, the NEMA data is very easy to understand. My only concern is actually how to get the data from the GPS unit to begin with, but I have some sample code I found on the net to get me started with that.

As for OBD integration, its not something I have setup, and wasn't planning to get it setup initially, so it can be added in a later version.

Acceleration/deceleration factor is going to be difficult to get right I would imagine, it's a lot of guesswork if you ask me. But reconciliation from manual entry will set the figures right again I guess. OBDII on the other hand will have all that data (distance travelled, speed, etc) so would I be right in saying manual reconciliation would not be required? Had a quick look on google, but does anyone know exactly what data OBDII outputs other than trouble codes?
