6 for applications where PowerPoint (large font) presentation
In boardrooms and conference rooms using video conferencing (Skype, Videxio, WebEx, etc.) a multiplier of 4 is recommended
4 for presentations that consist primarily of data rich contents such as CAD drawings, documents from Word or Excel, and Web pages or screen shares

· 4% EH—used when there are no clues for the viewer and they don’t see the content for very long.
