It doesn't need to be 3 minutes and 15 seconds necessarily. Any distance and time will suffice if you want to do it on the map. Usually *if* I do it on the map, I take 5 minutes and look it up on the knots-minutes table.
What I want to know is
1) Does it matter what power of persicope (x1.5 , x6 or x12) I use for the U-jagd?
2) What is the error on the speed measured by the U-jagd when the ship is at a big angle (say, AOB = 35°)?
And 3) My original question

-- why are my torpedoes missing even though my maths seem to be correct?
I'm a physics student with a minor in mathematics -- my math is usually correct with respect to these things. So I guess it's gotta be an error in torpedo parallax or another measurment error?
I'm tempted to step away from the parallax hypothesis because I tend to keep my gyro-angles under 10°, which should reduce the parallax effect, yet I keep missing or barely hitting the bow.
