(REQ) Slower U-Boat Dive Times and more accurate handling

I'd vouch on that too. I think the dive times listed in literature are always basically minimums and probably belie the real operational ones in complicated circumstances or when the attack was unexpected. I personally suspect that unless they were on top alert and with some of the tanks pre-flooded, even Type VIIs would probably take well over a minute to dive. I mean it makes sense to use a reasonably minimal value in the game, but I'd take a conservative estimate of that. Better to err on the side of long dives if you ask me!
