Peto!!!!!!!!! This little ditty is long over due!!!! Often when I'm detected and attacked I will go silent and deep. As I wait it out (about 15 minutes before the DD leave) I leave the computer to do other things. If I have to go silent for 4 hours I can enjoy the realistic counter attack and go do other things around the house. This opens up other aspects of the counter attack that can become a concern....battery life, CO2 levels. These two aspects just do not matter at the present moment. 15 minutes and they are gone, I surface and start the chase. Nice work
