I love the inclusion of highlighted sections of the page, to get more personalized feedback (and determine if anything is superfluous). However, this fails to show the interplay of content on a site. My hero image may be poignant or include an astrisk, but if you were curious about the process or deeper content, that information would live below the fold. Having reviewers see your entire page first, but then provide feedback on the highlighted section allows me to interpret the strength of copy similar to how consumer consume it today.
