Exactly, this is quite realistic. Once I was sitting securely on the bottom of Pentland Firth (S of Scapa) at 70m. Looking with free cam to kill some time, how my enemy couldn't find me and started to drop DC shallower each time until he blow off his rack
He was still around for an hour (?) but suddenly turned around and went his way west through the channel. Few minutes later I was struggling with rain of DC from a truly skilled DD, not just a rebuild trawler ... (not) nice
