Of course, keep in mind that I'm in the desert. There's not a lot of trees or anything blocking the gps.
Yeah, I never look at the speed unless I'm pulling (so I don't inadvertently surge or slow - don't have a PM).
I think the problem I have is that I live in the veritable jungle known as N GA, so the GPS isn't as reliable over the entirety of a given route.
When I'm on my "B" bike, which doesn't have a magnet, my recorded files look like a richter scale readout after a mag 6.5 quake.
(Yes, I'm being hyperbolic, but not by much!)
