The track width is about 20 M, which is an estimate of GPS
positioning accuracy and chart resolution. If the track width touches a rock, so may you if you are following the track blindly.
If you are positioned on the track line, all you can really say is that you are probably somewhere within the highlighted band.
Let us not forget that most of the charts
we use were compiled years ago, with crude instrumentation. Super accurate GPS
will not fix that.
And overzooming on a GE2KAP chart is a scary thought. Do you really trust GoogleEarth georeferencing at the metre range?
Anyway, turn it off if you don't like it.
