Here below is the TMA picture with solution on enemy sub which is traveling course 89 speed 04 and range 9489.
It so happens to be nearly 99% true solution (I used "show truth" to confirm target data and its bearing and position). Moreover target sub has not changed course or speed since beginning of its trackng.
My point is that TMA does not look like conveying this. Stack is all over the place! If I was to try to get this solution
just from this TMA alone I think I would be really hard pressed to place target in this very spot. What do you think?
