6) after the 3 minute rule I calculated the speed of the target: expl : 10 knots
7) I calculate the distance the target would move on his traject : 0.514444444 * 10 = 5.144 * 180 : 925 m
8) I draw a line of +- 925m on the course : this is the spot my torpedo will have to hit the object.
9) I draw a line from the 925 m mark to my sub icon and check the degrees
10) I put data in the TDC : fast T I, in this case 15 degrees to the right and shoot the torpedo

Your distance/ time math appears correct to me ( 925m would be covered in 3 min at 10kts). However are you taking your angle on the bow from where the target is currently or where it will be at impact time? Im pretty sure it should be what the angle is at launch time. Other than that I would say to get consistant hits at 4000+m you will need to fire spreads instead of single shots.
