STORAGE (INITIAL <SIZE>)?

     ORACLE-L Users,
       I have spent considerable time struggling with understanding
     Oracle's formula for determining the STORAGE (INITIAL <size>) value
     for Tables and Indexes.  Oracle7 Administrator's Guide devotes 5 pages
     in chapter 8 to the process for Tables.  I managed to decifer it to
     the best of my ability and placed the formula in an Excel spreadsheet.
     The results appear to me to be on the high side.

       I also recognize that these are "estimates" and a part of the
     "Tuning" process and in a production environment require regular
     monitoring/tweeking.

       Are there any other formulas or tools out there that I might try?

     Thank you for your help.
