thats wierd jim. i clocked b to g on the car trip and got 11.8 miles verses your nokia's 10.5? can different driving lines give that much difference?
also going off my cars trip computer(so probably not as accurate as your nokia) i averaged 75.6mph to your 72.8. i also matched your highest speed.
but that was just off my speedo so is probably a fair way out at that point.

very well done though you will have to show me how it's done next time.
