Wayne, It is best to follow the recommendations in the DFSMSrmm Implementation & Customization Guide. They were written based on lots of experience with many different installation. The CDS utilization is simply HURBA/HARBA * 100 It makes no account for empty space in CIs or CAs, nor for the potential to grow the CDS into multiple extents.
To determine really what space is actually used, you could define a VSAM KSDS like the CDS and repro the records from the CDS to the new KSDS and see what the HURBA/HARBA is then. VSAM is now very good at reusing empty space within already used CAs and CIs (CAs with R12+).
