[St] Speedometer accuracy

["Kevin Liske" <kevin.liske@xxxxxxxxx>]

I recently borrowed a Garmin Rino 120 from work to take on a road trip.  I
put it on the trip computer settings.
I had speed, max speed, average speed, odometer, and a few other readings.
It seemed that the Garmin odometer matched the bike odometer very closely.
I did notice that as my speed increased above 50mph, there was an increasing
variance in
the readings of the bike speedo and the gps speedo.

Bike     GPS
40        40
50        49
60        58
70        66
80        75
90        83
100      92

I have two theories.  1)  The bike speedo is actually inaccurate at high
speed.
2)  The bike speedo is correct and this gps can not process the signal
accurately
enough to be correct while moving at high speed. (This is a hand unit
designed for
people walking around after all and just may not have the specs to handle
high speed.)

Any thoughts?
