Actually I dunno...
(funny how we're arguing on behalf of each other now

)
After I typed that response (early this morning) it dawned on me that I was thinking in reference to a relative motion plot on a maneuvering board where all lines would radiate from the center.
In your case, you're plotting bearings on a DRT (dead reckoning tracer). The inherent motion I was thinking about
I believe is accounted for in your update of OwnShip's position. Your plot looks more like the TMA lines in Dr.Sids Least Squares TMA solution example rather than one of my relative motion examples.
In MoBo there is a TMA tool that will do the measuring between the lines to help determine the target TC. Would you mind if I worked up an example or two on MoBo? ...for the benefit of those who like to use it. Of course, it would be even better if I could enlist you to do it for me.
Your example and Dr.Sid's original examples are both currently not represented with tutorials in MoBo. However, since MoBo is both a DRT and a Maneuvering Board, it is perfectly capable of handling the technique.
Incidentally, what graphics program are you currently using to create your tutorial images?
