Well I suppose when you think about it, the actual skipper just called out what he saw and bearing/radians of mast height if he wanted a range reading. The rest of the team figured out the solution, and the weapons officer would calculate and set the torps.
So I suppose playing with auto targeting on isn't exactly unrealistic. It's all how you look at it. Plus there's a bit more of a rewarding feeling when you crunch all the numbers yourself. I like math
