But getting back on topic...

Not entirely, Tiger... you were close. It's not fatigue life - it's how titanium reacts to the compression forced on it by sea pressure as an over-time situation. IE, over time when at depth, the deeper it goes the more fragile it becomes, hence the reason the ALFA kept having to reduce it's operating depths.
At least, assuming I've been given good gouge myself.
