<DIV><FONT size=2 face=Arial>There are some odd cases where even GPS averaging
is not accurate enough to 'micro adjust' a way by 1-3
meters. One of which is where the sensor is inside a vehicle
(not rooftop mounted) on some curves. I
observe this by comparing multiple traces from multiple units and the
fact that they do not converge on a very good aerial image - even though
the entry and exit traces match very well.</FONT></DIV>
