Ok. Why does top speed matter? Who cares if it's a + or - a few kph?
Personally, when I spend $250 on a GPS, I want it to perform the functions it claims it's supposed to. One of the big boons of GPS is supposed to be "sensitive" speed and distance measurement. If it doesn't do that, I've senselessly wasted $$ over a $50 Cateye.
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:
