redyaris, what do you think, which is (more) off: Gray's odometer or google maps?
I just had a look at your log (what else could I do at the end of a night shift?) and I see that on your last trip there was a considerable difference.
I see the same phenomenon with Teresa, and all other sources I can check consistently imply that it's her odo that's off: google maps, road signs, Ciliegia's odo, and even her own odo before the tire change... which seemed already off to begin with. That's why I use that magic 1% correction lately (a very conservative estimation). I'd like to check it with GPS, but it seems it won't happen with this crappy software of my phone. Anyway my commute is 1.6% longer by google maps than Teresa shows it (24.8 vs 24.4km).

Over that trip of yours the difference was 3.5% - quite serious.
