TDC vs Position Keeper discussion

The degree change is the offset you use.

As joea mentioned, this is the way the TDC worked in real life.

There is a simpler method. Do everything normally, lock on, enter AoB and speed, then enter range. Then just before you fire, unlock the scope with the L key, aim the scope at the part of the ship you want to target, then hit the transmit data button. The TDC will update the solution for the new bearing. It's a lot easier than going to the torpedo data screen and trying to input an offset manually and it shouldn't take more than a 2-3 extra seconds.
