Indeed it did.

In my extremely biased opinion, that spreadsheet is a true work of art, pushing the limits of what can be accomplished with Excel.

Many thanks to Alvin (aka: Mach) and Paul (aka: pgrzelak) for the many hours of help they have given me with this project.

If anyone would like to see the final result, send me a PM and I'll email you a copy. It's about 520K, although I guess it will zip down to about 200K.
