Great post!
I get good accuracy with the TDC, including one hit out of a narrow spread of three torpedoes on a tanker from over 5000 yards last night.
My simplistic method that is working for me is:
1. Set torpedo speeds and depths as I expect to need. Open outer doors.
2. Select and identify ships I wish to attack.
3. Aproximate angle on the bow based on convoy course, but do NOT enter the data.
4. Target the first ship to be attack and range it, entering the data.
5. Quickly fine tune angle on the bow for this target and enter it.
6. Repeat steps 4 and 5.
7. Get TDC generate speed estimate. If it makes sense, enter it. If it seems off, repeat steps 4-7 until I get a reasonable speed generated (I only have to repeat the procedure 1 time out of three on average, and usually only in rough seas or at longer ranges where by AOB estimation was off.
8. Launch torpeodes and watch the fireworks.
