If you think about what is happening, you are constructing a virtual target in your computer, the TDC is the torpedo data computer, and making it move in the same place, speed and course as the real target. Let's enter the info in the wrong order and see what happens. First, flip on the PK and figure out the speed. It's 5 knots. Enter that into the TDC and the virtual target at whatever range the TDC already has (has nothing to do with your target!) starts moving on whatever course is already there at 5 knots! Then we'll measure the range with stadimeter. Now for a brief instant, the target is positioned on top of the real one, but it moves at the wrong course at 5 knots away from the real target. It will continue to run away until you input an AoB, which tells the TDC what the target course is. Finally you measure the AoB, the TDC position has now run away from the real position quite a distance and is moving the same course and speed. If you shoot, you'll miss. Understand?

Now let's do it right. First, enter speed and course to tell the target position which direction and how fast to move. ALWAYS LAST, do the stadimeter measurement to tell the TDC where he is. Then the TDC will plot the position and IMMEDIATELY begin to move it at the same course and speed as the target. It will remain right on top of the target so long as your measurements are right. You can check this on your attack map before you shoot. Provided your torpedo tube doors are open you will hit where you aim now.

Many problems with manual targeting accuracy come down to something as simple as what order you enter the data. Nobody covers this and I don't really know why. It's vital if you want to sink your enemy.

Many thanks for this, RR!!!
