Though reading too much into wargames is also a mistake - they put significant limits on the sonar power as otherwise it would devastate the local ocean ecology, which naturally benefits those who want to remain hidden like submarines in exercises. They're meant to use estimates and an honor system of detection, but I've generally heard it's pretty laughable from people involved. I don't doubt that such ecological worries will go out the window if there's actual threats involved.
