Perhaps I should have been little more specific. I'm playing at 100% realism using the tools offered in the game only (distance using mast height, speed using 3:15 rule, no WO help). I'm only at 1940 with TIs and TIIs. I have yet to intercept a convoy but I'll worry about that later. I still find it hard to believe that people actually score a hit at 3000m or beyond (unless it's using a homing guidance). I think the biggest issue for me is finding the exact distance of the enemy ship. Especially when the water is rough whenever I plot the target's course it looks like a mess and doesn't represent anything close to a line. But then again I have missed a target at a distance of 500m when the water was like a mirror
