R. Bear, in the ocean we can not count on pulling our last stop at 10fsw as we can in a cave. At times the conditions limit this. So with that in mind we pull the shallowest (planed) stop at 20fsw. Although, if conditions permit, we will pull a 3min safety stop at 10fsw to subside some of the bubbling that will occure in that 1/6th of an atmosphere of sea water.
