Your last statement contains the most truth and most divers trained under NAUI/PADI/YMCA/SSI are "trained" to conduct dives to 60' for OW and ~130' for AOW. Experience not withstanding.
Those are some agencies not all agencies. Worldwide they dont even represent the majority of agencies. I fail to see why someone wants an "industry standard" to define something like that when simply saying dive to within your qualifications is more appropriate.
FWIW im BSAC and PADI so familiar with both sets of training.
I just cant fathom someone is trying to invent a definition when none is needed.
