The benefit is important. It is the first thing they teach you in sales. This is not how to win friends and influence people. In usability study reports, of course, the designers are primarily interested in your results, not your design ideas. Put blue underlined text on a page and a user will be drawn to click on it because of their vast experience with blue, underlined hyperlinks.
Experts agree here as well.
Jakob Nielsen insists that blue means links and should not be used for anything else. Good designs select one interface element for all site navigation, and follow their own guidelines for presenting that interface consistently throughout the product. Only by understanding the users can you judge the product or service. Only by recording that understanding can you ensure that you and your client share that understanding. No explanation of expected user populations can be found in the report.
