I can't seem to find a description of what the text or spreadsheet tasks were that were used to evaluate the efficiency of the users. Judging from the screenshots in the PDF linked to the story, though, they significantly involved moving things between two documents or pages. Granted, it is useful to know the relative efficiency of doing such tasks on different monitor configurations. But, unless this is the only thing all of your employees do all day, it's highly misleading to turn the efficiency improvement into a dollar amount based on percentage of employee salary.
