Oh, and another problem with the in-game stadimeter is its not "centered" on the periscope view. Depending on which direction you're looking, the stadimeter will produce a range figure error (up to a 20 yards @ 1000 yard true distance, much more when further away). This error is produced between the forward bearing positions and the rear facing bearings.

The stadimeter centering point is placed forward of the actual position from which the camera view originates. Since the camera view is what provides the double image of the target, the error is calculated into the range figure. You won't know it exists unless you have a mission made up with the Mission Editor of 2 of the same targets, at the same distance. One target is positioned to the front of the sub, the other at the rear. The found range will be different between the two. At greater true distances, this error becomes quite large in the difference between the front and rear facing targets.

Add up the other stadimeter short comings (and wrong height dimensions), its easy to see why there are players that say the manual targeting stinks with the game (except for using the sonar system, its dead on accurate). I for one play only with manual targeting. I know the problems with the systems, and will strive to provide the best fixes for them. Sure, you can simply get so close to the target that you can't miss, even with a wrong firing solution. But in real life, no Captain worth the scrambled eggs on his cap would risk is life and crew knowing his targeting system was so screwed up you would use blind luck for accuracy.
