Thomas - Perhaps the following distinction will help explain the inconsistency
         in the physical space numbers...

Physical occupancy                      The occupancy of physical files in a
                                        storage pool. This is the actual space
                                        required for the storage of physical
                                        files, including the unused space
                                        created when logical files are deleted
                                        from aggregates.  See also physical
                                        file, logical file, and logical
                                        occupancy.
Logical occupancy                       The space required for the storage of
                                        logical files in a storage pool.
                                        Because logical occupancy does not
                                        include the unused space created when
                                        logical files are deleted from
                                        aggregates, it may be less than physical
                                        occupancy.
                                        See also physical file and logical file.
