[I'm goin' down]

got it. I think I have worked out all of the issues with the mod. Now it is just a matter of practice. I have become a very good plotter. That last two mission plots had range and bearing readings that plotted in perfectly straight lines. My problem arose later in the first mission, when I overshot the target because I wasn't watching the Nav Map, and on second, repeat mission when my plots for speed calculation indicated the target was on a closer parallel course to the course plotted by four by range and bearing readings. I do not know how, on the second attempt, the target ended up on the parallel course, closer to my boat, so I exited figuring that the solution was bad and I would likely miss the target if I shot at it.

In any event, I think it is a matter of time before I start nailing the targets in TMs. Maybe this weekend...
