The guides are offered in two formats: Microsoft Excel (XLS) and Adobe PDF. To use the Excel guide, simply input the four data points to the appropriate fields and the calculations will be done for you in the spreadsheet. If you do not have Microsoft Excel, the PDF shows you how to perform the calculations. Sample data is included.
