Hooray!
So I just made my first ever successful 100% realism manual TDC attack using a combination of Hitman's instructions and the "law of cos" calculations that StarvingArtist posted, here:

Scored 3 out of 3 torpedo hits and sunk a Medium Old Split Freighter. Thanks Hitman and StarvingArtist & everyone else who's posted manual targeting hints here -- couldn't have done it without ya!
I'm still confused as all hell out how the whole process is supposed to work, of course, and I had to pause the game for like half an hour while making the calculations and dredging the forums looking for instructions, but it worked!
I'd previously tried several other manual targetting methods (mostly Hitman's) and could never get any hits -- my torpedos kept missing (mostly behind) by a pretty large margin. I was able to get the hits by pausing the game for a while and using the (fairly complex) cosine calculations to find Speed & AOB. I figure Hitman's methods probably work great but I was just doing them wrong 'cause I don't really undetstand how the TDC or PK work.
In particular I still can't figure out:
1. How to clear/reset the TDC/PK -- supposedly there's an 'X' somewhere that I'm supposed to click, but I can't for the life of me find it.
2. Does it matter what order I enter information into the TDC, or how long I wait between entering one piece of information and the next?
3. When should I be turning the position keeper on and off? Does turning the position keeper on with only one or two pieces of information screw up the tracking even after you've entered the final piece? (Like when I'd enter the Range, Bearing, and AOB -- but then waited a couple minutes before entering the Speed. It's like the PK would think the target had just been sitting still that whole time, so it would then show up on the attack map well behind its actual location....)
I also still have no idea how on earth I'd do any of this without having to pause the game for half an hour to do all the math and read instructions...
