I'm pretty sure it just sets the difficulty options.
I disagree on the "survival rate" issue. By the simple nature of it being a game, players are going to have many more opportunities to take risks and are going to take those risks out of all proportion to reality. There are also so many other aspects of the AI that are deficient and can be exploited that some redress must be made in other areas. Also, I'm not of the opinion that you should always be able to escape once detected. There were US subs in the war that weren't able to escape after being detected. We just don't get to read their stories.
I think that using historical survival rates as the groundwork for realism is going to prove very problematic. There were so many other factors that affected historical survival rates that is not going to be a good yardstick to measure realism against.
