@ CB :
I experienced that alone unshakeable DDs too CB, but it is gone after i touch the sensors angles.
About my experience at moment, i am sticky with to found an average setting to not have ubber or dummy DDs.
In this way i start up tp touch decoys.
As an experiment, and ashot in the darke, i rise up all 5 or 6 diferent decoys values.
I duplicated life time, and triplicated effective surface.
Saddly i can not manage noise, is the same problem than sensivity is a long secuence of numbers into the hexe file.
Any way i can copy the higger decoy noise value and apply it to all them.
the results is made a intentional provocation, against ubber Buckley and Evarts.
Then when detected, i lauched 6 decoys all at same time.
Was an spectacle, all 5 DDs was around the decoys as "flyes around honey" launching all they have onboard, helgedogs, barrel depthcharges.....
I was able to scape from that hell at silent running with any disturb.
Settings looks to be too much, these settings made the sacape so easy.
This fact can be used to manage ubber and that alone unshakeable DDs experienced by CB.
We can set files for a hard game play on crew rating 3, ( CB needs to rise up, others may be needs to drop down) and let the tweaked decoys to evade the ubber Evarts and Buckley DDs on crew rating 4.
