I just took the time for crash dive exercise (note that I played alone):

10m (Tower disappears in the water): 28-30 Sec. (this is absolutely accurate historically)

50m: About 1:10

100m: About 1:58

150m: 2:48

With an EMPTY negative tank (German: Untertriebszelle) it takes about 1min and 40 seconds to dive at all! So the negative tank MUST be filled when on Surface!

At greater depths the boat realistically takes on water, so you must take this into account when moving slowly: the boat will tend to sink bit by bit. I will try and blow the main Ballast tanks A TINY BIT before going real Deep to compensate for flooding. (Trying all these things is so much fun I cannot believe a "game" actually let´s me do all this fancy "U-Boat stuff". So far I didn´t fire a single Torpedo, I just love to OPERATE "Das Boot"!)

Maybe the compressed air-behavior is correct, considering the fact that you only Need to get rid of SOME water to make the boat raise. However, the surfacing Speed is way to slow I´m sure.
