Hold on folks... My wife is a large breasted woman and needs ~25lbs in a skin, and ~34lbs in a 3mm suit... It could be an honest mistake.
BTW, I'm curious: What does the lift of a BC have to do with this?
No exposure suit... no weight needed there. The only weight that you would need to counteract would be the tank and possibly the BC material itself. Most fins are slightly negative. Since there was no suit I would presume there was no other neoprene worn, so if the BC lift capacity is 30lbs, it would have to be almost fully inflated to even keep her neutral underwater, especially at the beginning of the dive when the tank is full of air.
If she was wearing no neoprene, at depth she would be over weighted and even a full BC wouldn't float her up without kicking (with a full tank).
