A few months ago I set up a test mission with several enemy warships at different ranges around an submerged sub. Actually I had saved two identical test setups, one in daylight, the other at night. I reworked the stock "AI_Sensors.dat" file to only have
one particular sensor working at a time (its tough to know what exactly detected the sub in certain conditions). My tests were to just work on the subs detection with visual AI. One during the day, the other at night, and eliminating the other possible sensors detection capabilities. I documented the amount of time it took for an enemy ship to detect the sub with a partial periscope rise; a full periscope rise; a partial sub surfaced position (decks awash); and a full surfaced position. I took into account various distances that were between the sub and target ships and attempted to see when an enemy could detect the sub, and when it couldn't. The seas were calm to remove any "Wave Factor" multiplier.
I found some surprising things.
Specific to the visual detection, I found the "Light Factor" actually is backwards to what it should be. In other words, the higher the "Light Factor" figure, the easier it is for the AI to detect the sub at night. Dropping the figure helped in preventing night detection, it also lowered the ability to have the same sub detected during the day! A sub sitting off from a warship at a very reasonable distance was not detected at all during the day. Actually, like in the stock game, they could be made blind as bats during the day, yet detect you quite well at night. Just the exact opposite of what should occur. Because there seems to be a "default" setting for the night time detection, there was no way to get away from this backward detection. I'm not surprised about this with the game, I've seen many issues that have been revealed to be wrong with the games mechanics.
Another thing is the fact that no two detections are the same. There seems to be a random generated way the sub is visually detected, even though the sub is put in front of the enemy equally. One time the sub is detected within a few seconds of exposure, the next time it may take a couple of minutes. If it's detected at all! This made my testing needing to take an "average" of the subs exposure/length of time calculation. No two are alike in detection time.
So what's it all mean?
Well, it means if you expect to have the game allow you to sneak up onto a target under the cover of darkness, you can forget it. Not without throwing off the daytime detection to the point of absurdity. It also means you need to take several tests of the same ship positions in order to get an average of detection specifics. No two are alike. This also means a players ability to slip by a specific enemy is totally random; trying the same mission another time, will probably give you a different result.
