2. Aspect Ratio is one method to get the AoB. However historicaly rarely used due to many reasons. At first you must know the aspect ratio, that was not always the case. Then it was less acurate then it appears in sh4 because it was very hard to hold the scope on one place with a boat being shaked around in rough sea. And after all it requires to have the periscope raised for to long time.

Altirnatively you can take two position marks and make a plot. That will not only provide the course (which can be converted into AoB easily) but the speed also.

Basicly youre doing it anyway. When you get speed you also have course information. Just tune in the course in TDC compas and you have your AoB. No calculations needed.
Yeap, there is on guy who knos how to use the TDC and KP, though KP degreads rapidly. I learnned how to use it from your video tutorial, though i do not take just two measures, the first on when i idenity the ship cause is ussually pretty far still and is not very accurate, i take 3 4 or 5 depending on the situation although the longer the time between measurements the better, is also true the farther the ship the worse is range accurate. I found a way in between these two parametrs that usually works for me.
