Not a stretch at all if the wing/bladder was not used prior to the dive. That's like trying on a sock right after you got it out of the wrapper and there's a hole in the big toe. Did you do it?
The brand-new sock is tested overnight prior to being carefully packed for shipping. After receipt the sock is stored for two months. It then gets taken out of the wrapper and packed in luggage and tranported internationally. It gets loaded on a dive boat, and the hole is noted. And you think the guy that tested it overnight is at fault?
At least now were looking at apples to apples.
