This is a TECH class we are discussing. Not someone who just has OW pushing their limits.
However, MAYBE this specific class was being taught to people who already spearfish at those depths on air. Maybe they decided to take a class and learn how to add a little He into the tank to possibly take the buzz off?
That doesn't imply that standards shouldn't be followed, but if applicable, it might provide a broader perspective on what those photographs depict. Although I admit, that "Dorsal Fin" (and upside down) pony bottle mount was disconcerting.
