TMA ...rather iffy.

Its TMA, not radar.

TMA is an estimated position over time based on your and your target's motion.

Travelling at 2 knots isn't doing you too many favors, btw (in terms of TMA). You want larger numbers in terms of bearing spread over the course of a leg.
Speaking of, when you change direction and speed- your TMA crew expects to see some error in the current solution. That's how they refine the solution so it fits better.

Also, remember that TMA is always in the past.

Try this, instead:

-You get your initial contact to the target.
-Maneuver the boat so you can track and close slightly on the target.
-Keep a constant course and speed for a six-to-twelve minute leg.
-Refine your solution.
-Change course by 10 to 15 degrees and/or change speed by +/- 3 knots or so.
-Keep a constant course and speed for another six-to-twelve minute leg.
-Keep refining your solution at the end of each leg.
-Rinse and repeat until you get to your firing point.

Just IMO, I'm more than happy to have a target solution that's within 1,000 yards of the target's actual position.

Anything within 2-to-5 thousand yards in terms of accuracy is a shooting solution.
