Hey fellas,

This is my first sub sim game, but I'll be ****ed if I'm going to play with automatic targeting. Unfortunately I'm having a tough time figuring out the art of TDC targeting. I would like to perform a test with you guys, and see what results you come up with. And if you prove yourself better than me (not hard), perhaps you could give a few pointers.

Here is my problem. I'm approaching a C2 Cargo ship at about 1000 meters and 35-40stb AOB. This is where I have a save in game. At this point I start entering data into the TDC. (**By turning off manual targeting in the realism settings, and then restarting the mission at this save point, I know EXACTLY what the cargo ships course is**) The exact range is 1000 meters... and within 10 seconds of starting the savegame, it's closer to 900. So within TDC, I take a height measurement that gives me roughly a ~950 meter range. No problem. That measurement should be accurate. Next I take an AOB guess. Since I know the EXACT AOB is 35-40, I just "cheat" and put that in right away.

Now comes the tricky part that screws me up. To collect speed I start the stopwatch and let it run for 10-15 seconds. Everytime it gives me a speed of 3kts or 4kts. Now, I KNOW the speed the cargo ship is traveling at is 6kts. So, even though my range measure is pretty **** accurate... and I know my AOB is dead on... it always underestimates my speed measurement. As such, my torpedos are always behind... sometimes by a full boat length.

Here is a picture of my data right before launching:

I'm going to post my savegame for anyone to download and compare results. Immediately after the game loads, hit F3 (attack periscope) and target the C2 Cargo ship right in front of you. Within 10 seconds you should have range and AOB entered. Add another 10-15 seconds for speed calculation, and then fire. That's what I've been doing... and it's not working for me. The savegame is called 'TDC Test'.

Here is the savegame file(s):

Here is where the files go on your computer:

C:\Documents and Settings\*****\My Documents\SH3\data\cfg\SingleMissions

I guess my main question is why the TDC computation is giving me such a low speed calculation... even though when I know my range and AOB are correct. Because of this, I'm always shooting behind the target.

Am I approaching this entirely wrong? Am I not suppose to wait until 1000 meters before collecting data? I notice the Gyroangle says the exact same reading as my periscope bearing. Is the gyroangle not supposed to be the calculated angle at which a torpedo shoots to intecept the moving target??? Is my TDC data not getting inputted?

Thanks for anyone that participates and shares their results with me.
