With the research in gas densities and narcosis being significant at shallower depths then historically considered what is your personal minimum depth where helium becomes a reasonable necessity for your dive plan? How deep a dive would you cancel and not dive if helium was unavailable? Side note: recognizing conditions, availability and cost also dictate this decision. Making a meaningful poll factors are limited. Assume 'normal' conditions for you.
Rough poll attached. Also curious what has helped form your current assessment.
