Im quite steady at < .5 cft/min with a shorty, al80 and my camera rig. Introduce the drysuit and things change for a coupe of reasons - first of all more insulation means more weight to push around. Also when I dive dry I tend not to be just swimming around looking at and taking pictures of cool stuff but actually work in some way, shape or form and the sac can easilly get to .8-.9 cft/min depending on what Im doing..
