This is not the only thing I ment.
Having equipment like this, allows a freediver to actually have more bottom time, as well as a quicker ascent.
In my opinion, bottom time (in deep dives) is even more important than ascent rate. In the case of Carlos Coste, the dive profile shows a total bottom time of around 3 minutes bellow 100 meters. So if Carlos could come up faster but slow down during the last 40 meters, things MIGHT have been different. A fast ascent rate makes the situation worse in the last 15 meters, but the main reason we get bent is the accumulation of nitrogen in the first place. And this accumulation happens much faster at depth. In other words, it's the whole dive profile that matters, not only the ascent rate.
And, in my opinion, a device like this, allows for bad profiles. Not a bad as diving with a scooter perhaps, but still bad. And in any case, worst that constant weight freediving.
