Default Any tips for four bearings?

I'm not sure what I'm doing wrong, but my four bearings checks are always incorrect.

I was completely immobile here, 0 knots, and taking bearings every 10 minutes on a closing merchant.




Bearing 1 is the furthest left, Bearing 2 is middle, Bearing 3 is rightmost. I made 2 parallel lines from bearing 1 and 3, dropped them so they intersected mark 2, and that gave me intersections at mark 3 and mark 4. This should determine the course, right?



So then I start an on the surface run in the general direction and a different angle so I can get the real fourth, but in the interim I make my predicted fourth. To do this, I make a radius from where the course intersects bearing 2 to where it intersects bearing 3 (mark 4), then drag and drop, make a fourth bearing from my original position to where the radius intersects the predicted course.



So after another 10 minutes my run is done so I drop, get a final real fourth bearing and it gives me this line. Mark 6 is where my new fourth intersects the predicted fourth, so that is, from my understanding, where the ship SHOULD be, and then I dragged the course line down. Then the distance between where this course line overlayed on the real position intersects the third bearing and the real fourth should give me their speed? For this I got 3750 meters in 10 minutes or 12.15 knots.



So I setup in an attack position on the course and decided to turn on visual contacts to verify I was doing it right and... I wasnt. They were far away by a large margin:



In fact their real course wasnt even close



I'm really not sure what step I got wrong here, any ideas? I've not been able to get an accurate position or course no matter how many times I try. The tutorial in TWOS with the automation thing is broken so unusable. When it gets to the time accelerating part, it just kinda breaks and no ship spawns and time accel never happens. Not sure what else to do
