| I e-mail the author of the article saying I wasn't sure he was correct on that point, no reply yet. Don't think he actually dives the unit much, just did a course.
I think he was getting confused between "saw tooth" profile dives. Bad regardless of if your on OC or CCR. But on CCR you use a lot of gas as you dump & refill the loop.
I recently did a long dive on the Zenobia, did 25mins @ 42m, 25 @ 35m, 25mins @ 25 - 30m & finally 25mins at 20min. I'd call this a multi-level dive!
Unit worked well, racked up 30mins of deco on initial deep leg, but it didn't increase as I came shallower (as you sort of expect)
