I think the GPS will be VERY accurate. I'd say the figures you're describing now show you have the TS nailed. The analog gauge is reading right where I'd expect it to be, and if the Gryphon and the GPS match, that's as good as you're going to get it.

Jack, did you use a GPS to confirm accuracy? I've run into an issue and am not sure how to best ensure accuracy.
I realized that my TomTom GPS does not have a standard odometer. The only way I can confirm distance is to plan a route and see what the total distance is to the destination. For instance, if my route says it's going to be 25 miles from A to B, my odometer is accurate if it is showing 25 miles when I hit my "exact" destination, or when the remaining mileage on the GPS hits 0. However, I've been told there is an approximate 5% leeway with the GPS, as the mileage adjusts and may vary over the entire route distance.
The other night, I ran 22.8 miles (according to the GPS). When I hit 0 on the GPS, my truck odometer was at 23.3, a .5 mile discrepancy. This tells me that with a TS of 2275, I am slightly over. However, it was weird when watching the GPS, becuase it seemed to be dead on, i.e every click down on the GPS, there was a simultaneous click up on my odometer. A few times during the ride, this sequence must have varied, but visually, it was unnoticeable without keeping my eyes on it the entire time. I did however watch both readings for over 2 miles straight with no variability.
Any advice on this??? Thanks in advance
