As to the amount of time destroyers spend hunting you in SHIII, part of it seems to be the routine that governs time spent away from the convoy. A lone destroyer or hunter/killer group should stay with you until they are sure you're dead or have lost contact for at least an hour. The ones tied to escort duty don't have that luxury. In real life spending too long hunting for one submarine could allow others in the area to attack too easily. The escorts have a time limit between when they lose contact with you and when they return to their escor duties. After all, keeping the enemy away from the convoy is as good as killing him, if he's too far behind to resume his attack.
One of the problems with SHI was that the destroyers could be too tenacious.
