Is is possible to define the width of the track when setting the start point for G-Metrix data.
I use my VIRB Elite to capture my automobile racing activities. On many tracks cars are released to the track via the pit road, immediately adjacent to the active racing surface.
My observations are that when I set the start point at the designated point on Pit Lane the Lap Counter & Timer don't activate on the racing surface. If I set the start point on the racing surface then when I go past the designated line on pit lane the Lap Counter and Timer quit working.
I know these action cams are used under all kinds of competitions - some where the distinct track surface goes very close (10 feet - sometimes less) to the timing line in the course of a lap; in my case the timing line might need to be 100 or more feet wide.
