I think it is more efficient to kick softer and softer, starting at 10 and stopping at 20. That way your speed will be more constant. For 30 meter max diving, neutral about 10 might work better (that's recommended for target dives) and you definitely need someone watching you for a holed up grouper in 30. Back in the 70's, the three man Italian team died with a grouper in a hole shallower than that during a world meet in the med, if my memory is right.
I don't understand packing as much as I want to. Sometimes the first pack of a session, I start to feel like that and exhale right a way. Blood pressure and heart rate changes are probably involved. I've also seen a young healthy swimmer black out after diving into to cold water when he was warm and dry (very deep inhale but no packing).
That was a very dangerous dynamic. I would stop packing except for dry lung stretches and please, no diving or training without a safety.

P.S. Just read Jeff's post and remembered that one of the best in the world told me that he only packs if needed for clearing.
