On Second patrol now, have two merchants down by torpedoes, with three torpedoes left. I've had misses but also premature explosions and suspected deep runners.
I've had some misses though, which upon analysis are attributed to issue with proper final firing bearing. I've got the speed (metric system took time to adjust to for plotting) but the weakness is the final firing bearing with german TDC.
In the US TDC, you place the crosshairs on desired impact point, send final bearing to TDC and fire torpedo, send updated bearing, fire again and so forth or place on middle or target, send bearing. Wait for five seconds, fire, wait, fire. The TDC updates the bearing constantly, the advantage of the position keeper on US TDC.
With German TDC. What is the best way to fire on final bearing for accuracy? To lock in that final bearing.

Center mass of the target. The biggest advantage of the German device over the American one was the direct transmission of the bearing from the optics to the computer. Remember the German device is not position-keeping - once you ascertain the AOB, you switch “on” the TDC to update, and from then on as you follow the target, the AOB updates as the bearing changes. This is a result though of you turning the optics. This made it so you didn’t have to shoot “im Durchwandern” (meaning placing the optics on the “shoot bearing” and waiting for the target to cross). You could follow the target with the optics, the computer’s bearing is tracking with the optics, and best case you fire when the gyro is low.
So in practice in game (different than in real life since SH TDC lacks functionality):
1. Gather your data using whatever method you prefer and note it down.
2. Once on your final attack course, set up the TDC with AOB and speed and the range you will likely fire at.
3. Switch TDC to start tracking.
4. Follow the target and watch the AOB develop, adjust as necessary.
5. Watch your gyro angle on the TDC and fire when the gyro is within 20 deg of your bow, aiming at desired impact point. Low gyro is not necessary but eliminates range as a decisive factor.
In real life (not relevant to game but if curious):
At any point, even before diving to approach, place optics on target, set AOB into the computer, switch follow switch on TDC to accept bearings from optics, and turn on the AOB motor. From now on, as long as the target maintains course, AOB need not be touched again - the computer will take all own course and target bearing changes into account to maintain the correct AOB. This was the major advantage of the S3 over the previous models.
