I just PM'd him now but it looks like he doesn't frequent these boards all that often.

Yeah I believe so as well. In fact when I'm done with my VII career I'd like to start a new one with a XXI and use this technique almost exclusively. Although like you said I still like to use the periscope to get a visual ID of what I'm targeting and to refine my firing solution.

For me, there are two kinds of situation where the conditions are not favourable. Firstly when the intial AOB is very small, the changes in bearing at the beginning are too small to be helpful, and then as the target nears the changes are too large to be able to make the third "bearing prediction line" with great accuracy.
Secondly, when the initial AOB is large, or the target is moving fast, the 16 minutes wait time means that you cannot intercept targets which may be reachable using other techniques (unless you are prepared to run on the surface without sonar contacts at all)

Aye I've found this out as well when I began learning and using this technique.
