What is the best way to plot my sub and my target to determine the AOB? Can i use my attack map?
Sorry, slightly struggling on the manual TDT although the video really helped minus this one areas.

Angle on Bow: it's the angle formed from the course of the coming ship and your sub position.
As such, it has nothing to do with your sub heading or periscope bearing. But the periscope bearing will give an
estimate of the target angle on bow, provided that the sightings and numbers collected over the time of target tracking are valid -
initial angle on bow, initial speed, initial range then
angle on bow 2 mins, speed 2 mins, range 2 mins. This is the thing about old subs. Only the trained eye, and experience IRL of the skipper that helped scoring ships, but that came in essence from previous experience.
To be straight, at first you'll have a hard time finding target ship speed, because the sea is not constant, and as soon as you pop scope, he'll do minor rudder inputs as in real life. then the angle on bow becomes difficult because the aspect: angle correlation which always changes with time and is never constant. Finally, the distance with a bugged stadimeter, a discrepancy which is reduced by sounding (which gives away your position).
Nowadays, subs have onboard computers and advanced optics to even see the brand of cigarettes the skipper is smoking. Tech has relieved the human factor.
