Lets just say that most GA types fly in straight lines from one Point of Interest to another PoI. These can be as close together as you like, depending upon how many places you wish to see on your flight.
I often despair of those who religiously keep to within 100 yards of their Magenta Line. What are they trying to prove? Have they never studied mathematics, such that they would realise that even a track difference of 5 degrees makes practically no difference to the length of the flight?... Just look up Cos 5 degrees to see how near it is to 1.000 to make no difference.
