I agree with maillemaker. You should try playing with map updates off. It really changes the game.

They did. Surviving examples of KM-issue trig tables can be found on the web.
They are if you are doing Real Nav. Real U-boat commanders used celestial navigation to determine their position. They didn't have a 21st century computer to draw little circles on the map. They had a navigator guy who had to calculate the boat's position. And sometimes, they had to check it themselves.

Before I learned how to draw the triangles, I used the TDC to calculate intercept courses by doubling the target ship's known or estimated velocity and feeding the data into the TDC. That gave me the right lead angle to travel at 15 knots to overtake the ship so sometimes I had to pad it a bit by, for example, adding another knot to the ship's speed if I felt I couldn't make 15 knots.

It's called a TVR. The TDC was an American device which was quite different in function to the TVR. And I don't know if it was possible to use an historical TVR the way you describe. If not, then you are just using your computer to do the calculations for you. That would be rather like using a scientific calculator, only easier.
