Well that's f'ing dumb. I wonder what the rationale is. One of the biggest benefits of ccrs is time and techniques to get your butt out of a pickle.

Because SCR on a vertical ascent like you would have in a an “air Dil no deco course” is dumb and not practical and honestly borderline dangerous. SCR is not designed for ascents.

It’s easy enough to carry enough bailout to make a direct ascent to the surface.

It very much has an important role in cave and other advanced CCR courses but in my opinion as zero benefit in initial level CCR courses.
