I should have been clearer. Sorry.

That's it. The best way to achieve this is to calculate (plot) the target's course and to take the right position in advance. Then, you can either use a one of the lead angle tables, or use the TDC: you entre the data that you know by plottind. The scope/UZO must be pointing 0°, then you adjust the AOB to the value it will have when the target will be crossing the axe of your boat, i. e. at the moment of it's death. For a 90° shot, it will be 90°. Just avoid confusing boards... Then you can turn the auto-update back ON and turn the scope towards the coming target till the indicated gyroangle is 0°.

Getting to the right position seems to be actually the hardest part of it all.

It isn't a bad idea and tactics-wise it's necessary. Remember than a real boat could never stay motionless, end they couldn't come to a dead stop submerged since they mould lose fine control of the depth. But I'm not sure if it is compatible with the 3.15 minutes rule.
Again, I strongly suggest using the mighty MoBo which allows you to do some relative plotting. Everything is fine as long as you move with a constant speed and course.
Your plotting may never be very precise (because of aur tools) if you take but two marks. Try some longer observations: I usually try to have at least three or four marks, taken with 5 minutes intervals rather than 3 minutes, and the target's vector is always calculated between the first and the last mark. This allows you to have a good solution in spite of errors in the measures since tese inaccuracies become statistically unimportant over a long distance.
Of course this requires you to stalk the target during some time and is most rewarding for night surface operations. But this is right: that's how most sinkings in early war were done.
Fette Beute!
