Problem is not with the escaping tactics, but with the tactics used by the AI. As I said, is completely unnatural and wrong how the convoy escorts are reacting now in IRAI. Leaving the convoy unescorted and even halt it for 2 days or more just to hunt a single sub is unacceptable.
In MP this would give a huge advantage for the players just because is enough that 1 player will distract the escorts then the others will just sink the whole convoy without any problem.
The stock AI tactic is oke, what it need to be fixed there is just the contact depth and the DC's. They loose the track of any sub under 80m and they cannot drop DC's under 50m. Even so, the DC's do almost no damage. That's the problem now with the stock AI, nothing else.
Ah.. and of course, for campaign is a must have the Elite Campaign mod installed. Just because the devs made the SH5 campaign retard friendly, so every ship in the campaign is set to novice and to use evasive manoeuvres, what makes them to not react at all to any threat .. just flee
