Hello!
I recently got SH III and now I am increasing slowly the realism settings, which is great fun indeed. (How proud I was when the first manual targeted torpedo hit!

) But now after turning off the last option 'automated map updates' it seems I have hit a brick wall. Without exactly knowing where the hostile ships are its hard to reach a good intercept point, let alone fire torpedos that hit correctly.
For example, how do I best calculate target range?
I understand the 'notepad method' for measuring range, and it works fine in a tutorial setting (calm waves, target 1000 meters away) but during a real campaign with stormy weather, when the periscope dances up and down and the ship is still a good 3 kilometers away, my measurements seem to be way off or its simply impossible to have the periscope hold still long enough to get a fix.
How do you calculate torpedo settings?
Right now I measure things out of the map and enter them into the TDC, as explained in Dantenoc's great "How to sink a ship" guide. But without map updates that's impossible, and as I don't know how get a ships exact position in the first place, I can't plot the ship in the map manually. *sigh*
I'd be happy about any help or tips whatsoever!
