TDC reset, how do you do it?

Correct that you don't have to reset it. I usually leave the TDC on for the entire patrol.

Once you have speed and AOB set correctly, one last range/bearing input will ensure the PK is tracking accurately. If you ever change speed or AOB you need to do another range/bearing input.

All that matters is that the PK is correct by the time you shoot. Inaccuracies while setting up a solution don't matter.

[EDIT] I basically seconded what Werner said above.

Another way to look at it is range/bearing tells the PK where the target is now. Speed and AOB tell the PK how the target will move in the future.

Once you have Speed and AOB set correctly (the ability to know future movement), one last range/bearing input (the current positition) will make the PK solution accurate, regardless of how much it was wrong due to previous activity or previous targets.
