If my Prussian helmsman can't keep within 1/2 of a degree of an assigned course, I'll be getting me a new Prussian helmsman. We aren't using the compass from a box of Cracker Jack, you know.
Actually, I don't mind the course being off as much as a degree, but if a plotting tool isn't accurate, I'd rather do without it. Matter of fact, I was in the process of changing back to the stock map symbol without the overlay when I realized what the problems were and figured I'd try fixing them first. Turns out it worked.
