I suggest changing the verbiage on the 'review' Strunk & White progress sidebar to clearly state that review tracking will start once the Strunk & White badge has been earned, and not beforehand. Several users (including me) were left with the impression that the review stats were already being tracked, and would simply be made visible upon earning the badge. Instead, we were greeted with an empty review history after earning the Strunk & White badge. Changing the expectations of the user via clearer verbiage in the review tab will help avoid the disappointment of seeing the empty review tab.
