im sure someone will come up with a definitive answer to this soon enough:hmm:
the definitive answer to whether your changing course of speed changes your TDC solution is:

change of your course heading=change of TDC solution required
change of your speed=no change of TDC solution requried

BUt changes of either TARGET course OR speed will require a new TDC soltuion

N.B.for small changes of your course (say +/- 15 degrees) when you are firing roughly perpendicular to the target at short to medium range, the error in your solution is not significant.

Calculating your data in the day for use at night is fine, so long as the convoy hasn't changed course or speed after hitting a waypoint - for this reason a final speed verification using the fixed wire method is useful
