I agree, the precision and perfect accuracy of player intell is unrealistic, but on the whole a basic knowledge must have been in hand for both sides?
Yes, and no.
OK, I'm really trying here not to offend. If I do, not intentional, but the door was opened and I was invited ...
You are both over-simplifying and over-looking too much about human behavior. Here is just brief sampling ...
All sides thought/assumed everyone was cheating (most were in some fashion), both sides were very concerned about 'black' ships, and then finally once hostilities opened, both sides knew that enemy losses were being exaggerated, but didn't know to what extent. Finally both sides hid actual losses from their respective public for long periods ...
I could go on for weeks ...
How to proceed: read memoirs from the commanders of the day ... Doenitz and Von Manstein are good places to start ... then you need to have experience with command. I don't how else to say it; either you have had people under your direction suffer as a result of your decisions or you haven't. Or let me put it another way; the book lists used in the study of martial history at say VMI or Anapolis as compared to say Berkley are just a 'little' bit different. They are different because the teachers at the institutions, while all excellent, have a different perspective.
I'm not trying to belittle anyone here, but at the same time life experiences do matter. They impact perspective. Perspective is what this is about. Nimitz' perspective was vastly different than most players ... to see how far, just read his commm's ... they have largely been declassified and you can download and read all of his missives from the entire war ... I think it is some 3000 pages ...
My perspective is; I have been a student of this for 50 years in various capacities. I have lost people who were my responsibility. I had 29 funerals in 3 days once. I work very diligently every day to avoid a repetition ... I have been mostly, but not perfectly successful, in that.
