Help. Speed not matching in TMA

It's most likely due to bearing error, since you only had a few LOB's at 20 minutes. Also, if you did any maneovering during your TMA logging you would have alone account for the inaccurate LOB readings.

Bearing errors. Are they my fault? Or is the TA inaccurate?

What do you mean?

That to have an accurate TMA the sub must keep costant speed (at least 7 knots) so that the TA is inline with the sub, costant depth and constant course.
If one or more of these conditions varies while you're tracking the enemy the lob will not be correct and you'll have an inccorect position of the target.

If while tracking you turn, you have to avoid to collect garbage (TA data when the array is not straight yelds garbage).

To avoid collecting bad data I used to speed up until the TA is "washed out" and hold that speed until the TA is straighly deployed again.

But I don't know if this alone did affect your solution that much.
