I have heard of people linking Excel files to the chart (via Imported Items, I guess?), but then I would have to have Excel on all my computers to view that data, wouldn't I?
Hmmm, wonder where you heard that?
My advice: Install Excel on every computer. Actually, you can go to
www.openoffice.org and order the entire suite of office documents for free. Open Office Calc will completely interact with Microsoft Excel.
Entering this kind of data is probably the easiest way to keep track of this type of data and Excel/Calc will do calculations and manipulate data in ways you can't even think of. The ability to add sheets on the fly is helpful and the best part about it is you can save it and send it to consultants for easy viewing of data.
