I've never used MoBo, so I'm not sure I'd be much help there. I didn't even know it existed until this thread.
If you could come up with a way to prove or disprove this method, that'd be great.
I know the part about an intersecting line with equidistant segments is correct. The only part that would really need tested is the method for finding said line when OwnShip is not stationary.
For my tutorial images, I'm just using PowerPoint and exporting to .pdf. PowerPoint is an excellent vector drawing tool if you know how to use it. I'm a vector-art fanboy... raster doesn't cut it for me. I've tinkered with powerpoint for many years and I've made some pretty complex images with it. I even used it to re-make Cap'n Scurvy's AoB circular slide rule. I posted
pictures of it here. It comes in pretty handy.
