This software helps orienteers to estimate where they're losing time - see my article in the BKO Newsletter of May 1996.
Download the software (53kb ZIP file; Current Version : V5.4, Date : 15/10/04, see update information ):
If your spreadsheet doesn't accept these formats, you can download a text description of how the straight line is plotted, and use it to write your own version.
