Just look this video and see your self how inacurate this method is.  ... |
Sure, if you use your GPS-ability, 5-meter-position, less-than-a-degree bearing accurate plotting party then it is going to be a piece of cake to get a speed (about 1% error on speed)that makes a torpedo get on target where you want. Even at 3 km range.
However, if you do not have those target ship contour icons on the map, instead placing marks plotting zoomed-out only based on periscope ranging or Watchofficer ranging then speed will only be accurate to about a knot. With 100m resolution on the ruler it doesn't get better. Now, if you fire at a common range of 800m-1km then that's no issue either. The target is many degrees wide (80 meters at 600-1km: 5 to 8 degrees). But at 3km (i.e. deep into a convoy) with less accurate and precise plotting it becomes a different story (80m at 3km = 1.5 degrees). If a 80m target was actually 0.6 knot faster or slower than 9 knots then it would have passed in front or aft. The game's campaign makes this easy because speeds are generally whole-knot values. But would real-life be like that?
