I cut those out of another screenshot I had of a different solution. :rotfl:
Sorry if they confused anyone, I was illustrating guessing AoB based on your approach and not actual torpedo bearings.
RR, When you say "sight right on the target" do you mean the point in space he will be at when he reaches 90 degrees.. ie your 0 bearing?
Edit: I also fixed the arrows on the original presentation to better represent the correct angles.
