Number of Tracklog Points

[Brian McG]

Is there a limit on the number of points used to create a tracklog?

The following pictures shows the tracklog in red with the intended route in blue

I am surprised that a tracklog which is supposed to be a trail of tiny breadcrumbs detailing a pretty precise copy of the path taken has so many straight line sections when displayed in MRA

doh! worked out what it is - loss of gps signal due to tunnels
