See it as a way to force the player to actually "man the stations" himself from time to time. Kind of forced immersion that may give you an advantage.
Situation #1:
You patrol in a certain area on time compression and just await for the programm to trigger an detection event and automatically return to 1:1 time compression. You can go through hours and days of "game time" in minutes of real time and may find a target "to play with".
Situation #2:
You patrol in a certain area and you decide that every one hour "game time" you drop put of time compression and "man" the radar/hydrophone stations yourself and do a sweep or two just if there is anything out there with the knowledge that you might pick something ineresting your virtual radar/sonar man wouldn't report (actually if you have radar you should always have it on until it detects something).
The real question then is which of the two situations appeals to you as a simulator player.
I'm certain that people here with better knowledge of how the programm works may advise you about if you can change the way the game "auto"reports contacts.
The orders from BDU you can more or less ignore if you choose so.
