Torpedo Experiment

Did you at any time use the lock key command to get the periscope on a target? Or moved either of the periscopes sideways?

It turns out that tube 1 and 4 often have a different lead angle from 2 and 3. I believe it's because they are on different sides of the boat. I did about 20 minutes of testing. I originally thought that opening the tube door changed the lead angle, but that theory didn't pan out.

Ah, definety intresting!
I never noted it, and your explanation sound logical to me.

Well yeah. If you use different torpedo types. But unlikely due to the tube having a position difference. That angle would be almost imperceptible.

It is likely is that you encountered the T1/T2 torpedo speed and lead update bug during your tests. (check the GWX manual known bugs section) I see you have different torpedo types in your tube. If the torpedoes have been set to different speeds, selecting between different tubes does not update to the apropriate lead angle. At some screenshots you clearly have type 2 in tube 1 and 4, and type 1 in tube 2 and 3.

Make sure all tubes carry the same torpedo type, and are set to the same speed. So this bug cannot have any effect.

Ah well, that was the culprit.
Anyway, at the start of a patrol I usually load two tubes with G7a and two with G7e... just to be prepared in case of a daylight attack (in which case I tend to prefer the G7e).

I remember this bug, but cannot remember the specifics.

Is there a way to negate the bug for the currently-selected tube? I vaguely remember that if you manually select the speed prior to firing it fixes the bug? Because I often start patrols with all T2s inside but T1s outside, and when I pull some in I end up with a mix in the tubes.

Here is what the GWX manual says about the TDC bug:

There is a bug with the Vorhaltrechner (―deflection calculator,‖ also referred to as the Torpedo Data Computer, or TDC) in stock Silent Hunter III
: the TDC does not always recognize when you have adjusted the speed of a steam-powered T I, T I FAT, or T I LUT I torpedo from ―fast‖ or ―medium to ―slow. The workaround is to always left-mouse-click on the torpedo speed selector before leaving the TDC view if you have changed the speed of a torpedo, as this appears to ensure the TDCrecognizes the correct torpedo speed settings. You don‘t have to change the speed setting when usingthis procedure–just click on the ―speed‖ button to ensure the TDC ―accept the new speed setting.
