My PC took a beating and I'm still trying to undo the damage. It's gonna be quite a while until I can get into the game. Too bad I can't post pictures either since I don't have screenshots. Anyway, here's a few things...

1. Never ever move the periscope when the TDC Autoupdate is OFF (in manual input mode). If you do, you mess up the AOB
2. Always unlock a target after you take the length and width readings. If you stay locked on the target, the AOB will always be wrong.
3. If you calculate the AOB, input it, then change your course, then fire, you'll miss. Every time you change course, you mess the AOB.

Forget about 1.5X zoom. There are 2 sets of periscope marks, the ones that you see when the AOBF is hidden, and the ones that you see when it's shown. As I said, the only difference between the 2, is that the AOBF ones are already doubled on the horizontal. A ship that spans 20 degrees, will span -10 +10 on the normal marks and -20 +20 on the AOBF ones. Since the Lock feature usually lock on the center of the 3d model, it's easier to just use the doubled ones.

So.. let's say you've spotted a ship (single, no escorts):

1. estimate AOB (no calculations, eyes only).
2. intercept at 90 degrees, based on that estimated AOB
3. decide if the target is moving slow enough to allow you to intercept it. If not, move parallel with it at flank speed until you overtake it by at least 45 degrees(when it's at your 225 or 135 bearing). Then do a T intercept.
4. as it moves closer, submerge (even warships will only spot you if they're bigger than 2 milirads or 2d mark on the scope).
5. at around 5000 meters you should be able to see it properly to do a reading (height + length). Write them down if you have bad memory and immediately UNLOCK the scope and don't move it anymore.
6. do the calculations but don't take note of the range, only the AOB.
7. enter the AOB, turn the TDC Autoupdate back ON and only now move the periscope to get 90 degree intercept course.
8. As you begin moving to that course reset your scope to 000 and reinput 90 degree AOB. From now on, any time you move the scope by mistake in manual mode, you can just repeat this step, set scope to 000 and reinput 90 AOB.
9. As soon as your target reaches 50 degrees AOB (at your 320 or 40 bearing) full reverse to bring your speed to 0 knots and stay there. If the target is very close you can just stay there, if not, you'll catch up later.
10. Start the chronometer and set your torpedoes in the meantime, you usually have about 20 seconds. As soon as the stern passes the center line stop the chrono and order a flank speed to catch up.
11. On the move, do a speed calculation and enter it in the TDC.
12. Immediately move the scope until the Gyro reads 000 (0 on the big one, 0 on the tens one). I'll call this the LOS bearing. If the target hasn't passed that point, you don't need to calculate the range. If your target is bigger than 4 milirads (4'th mark) you're close enough on any torpedo.
13.Shoot the torpedoes as soon the target reaches LOS bearing.
14.If the target did pass it already (it was too fast for you). Immediately do a quick range check and enter it in the TDC. Then move the scope over the target again and shoot.

And 3 more things:
1. the torpedoes take a few seconds to shoot and come to a full speed (even if you had opened the tubes). So shoot about 2 seconds before the sweet spot.
2. Speed input sucks in SH4. The dial is small (my bad) so you'll usually have a 0.2 knot error (better than the US boats tho, as they didn't allow for decimal speeds). So it helps to be as close as possible to your target.
3. Never use steam torpedoes. The target will spot them about 20 seconds before impact, enough time for them to full reverse and turn 90 degrees

As you can see, I've entered the final AOB at step 8, the final speed at step 11 and an optional range at step 14. The vids should be more helpful in understanding what that bloody AOB does. Hope this helps tho... Sorry Toten, you'll have to wait a bit more for vids.

I hope that in SH5 they'll allow us to input values even when TDC Autoupdate is ON. I also hope they'll link the AOB dial to the compass. Even so, on one attack, I destroyed 12 ships with 13 torpedoes in one single convoy attack (one ship took 2 eels because it was BIG). By single attack I mean that I didn't rechase the convoy to attack it again. It was all done in 30 minutes. That has to be a record. The poor Type VII only has 14 torpedoes!
