going after escorts?

[I'm goin' down]

While I may not be the best shot in the Navy, I am familiar with the various attack techniques and the easy AoB mod (my favorite). All of these are based upon tracking/plotting a target's course and speed. But destroyers change course frequently, change speeds, stop and go, and are sub killers. It takes time to track/plot course and speed, and with regard to a destroyer, there is not enough time to do the calculations, push the buttons, etc., or its course and speed changes so quickly that is has changed before you input and sent the data to the TDC, making the information input unreliable and usually inaccurate. Is their a solution (no pun intended) to this problem other than laying in wait and catching a destroyer while it cruises on a set course? If not, it means you will only have a good set up when a destroyer is not in the hunting mode (i.e. constantly altering course and speed) or a torpedo attack is implemented before it has spotted your boat and begun its attack run (which, although an attack run may be on a set course, the course change to an attack run happens so quickly that there is usually insufficient time once it has begun to plot/track or set up a firing solution).
