Thanks very much. I think you might have been correct on the stress-test as the instructor advised my before the dive that the shellfish featured everywhere at the dive site were very sharp before the dive as well.Sounds like it was a task-loading drill meant to be stressful. In actual practice, you'd leave the line and just exit. Come back with more gas for a cleanup dive.
Or, if you know it'll always be silty (i.e., it's tight), then you'd be bumping things enough for reference that buoyancy will be easy enough.
But hey, you got it done. Nice job!
Agreed with your point as well in that I would just leave the line and follow it out in a real life situation.
