I have posted this on a UK site but would be interested in the responses from the learned on here.
I think I remember reading somewhere that staying at 6m as opposed to reducing the gradient by rising to the 3m ceiling improves ISS on surfacing, but can't recall if it was gas agnostic or applied on CCR or just OC.
Obviously conditions or gas management or CNS clock may influence the decision but just wondered if anyone could confirm whether there is any merit in terms of safety in staying at 6m or vice versa and what the gas or loop considerations are that would influence the reduction of ISS on surfacing.
Typically I dive in the 50-65m depths for 30-45 minutes on a CCR.
