AOB and distance can be approximated and you will most likely still hit your target. But if you get the speed wrong then you might miss, even at close range.

What I like to do is to cross in front of the target (if possible surfaced). Once I have an AOB of 0° I know the targets course. I then continue until I have an AOB of 20°. I match the targets course and adjust my speed until I have a constant bearing. The targets speed is now the same as mine. Now I can dive and turn 90°. That way I don´t even have to estimate the range

A simple and effective method..... until they start to have escorts with radar, then it gets more complicated.

I like to get both the course and speed from where I'm shadowing, be it port, starboard, or in front. "Crossing the T" tends to be to dangerous for my tastes, radar or not; more movement = more chance of being spotted, i.e. I like 90 degree attacks too, so range/aob isn't relevant.
I don't bother trying it from astern; if you're going to attack you're going to have to move "up" anyway so I just do it then.
