I like to use stopwatch to calculate my position. When I have a ship sighted, I don t need to know where I am..just where I am relative to the ship. On safe distance I determine an approx course and speed before I dive (after flanking if nessecary )and make my attackrun, and keep plotting.I just use the strategic map to get distances and angles. As long as I can get to about one km distance on something like a tanker I must have miscalculated AOB and speed quiet a lot to miss
There are many ways to attack. I like this one. Never tried using attack map so I can t say anything about it. The attackdisc I like though , but I just use it as a helper to be as fast as possible to calculate new course/bearing when changing course. Can t really understand why calculating 34 degrees minus 74 degrees make me forget it s bearing before I started my turn haha.
