Isn't the TMA a little too perfect?

As I said you (and the manual) are correct when saying TMA maneuvers are essential to narrow down the possible solutions for the target.
However, the reason why ownship manuevers are required is explained in the following way:

An accurate firing solution is not affected by your change in course, as your sensors detect the track from the anticipated bearing

And that is, completely wrong.
