Fast 90, where am I going wrong.

Still, this does not sound like any proof or explanation of a solid method based on 2 bearings alone. Perhaps it is considered 'expert opinion' in that court case, but it doesn't show how it is done in practice. So that leaves nothing to verify it.

I guess you could do with just 2 bearings if you rely on the fading length of the line on the map, but that is nearing on cheating reality. With only a single ended line in a specific direction you cannot judge distance. So you can't plot 2 such indefinate lines and get a course from that. At best you can tell it has a course to either side if the bearing drifts to left or right.
