IFM Software Tools
During the development of our more robust platform independent tools,
we are making available a spreadsheet that you can use to calculate IFM.
You must have Windows XP to run this tool, or else if you are running
an earlier version of Windows, you can download an update that enables
you to view web-pages generated from MS Excel spreadsheets.
(* Please be patient. It may take a few minutes to load)
** Please read the disclaimers that specify
that this spreadsheet is distributed 'as is'.
