manual targeting problems are giving me inaccurate firing solutions

It might have something to do with what's posted here:

Instead of having to point the bow or stern nest on the intended torpedo running course, the torpedo actually left the tube, ran a preset distance and enabled, then under its own gyro control, turned to its running course. It proceeded on that course until it either hit the target or ran out of fuel and sank.

Thus, the "actual" run consisted of two straight segments connected by an arc formed by the turning radius of the torpedo.

In tests, both the attack map display and the TDC dials began to go nuts as the distance to target approached zero. It's possible that, once inside 200 yards (where the "running course" no longer exists), the TDC can no longer calculate the proper solution. Instead, the computer is stuck with only one (of the two) straight segments ... making it impossible to correctly connect them with an arc.
