We've all heard the lectures on how average speed is worthless... I don't believe that's what the OP is going after. He just wants to know if his GPS is accurate or not:
GPS is fairly accurate but only to a point. A few feet off one second and a few feet off the next second and it will think you are going a bit faster one second and a bit slower the next. Over a few seconds it averages out, it's not worth worrying about.
