Welcome to the Q&A Forum

Hi Ben, if it works in GWT but not showing in Google results, it's probably because Google doesn't think that page is important enough to show rich snippets. It is probably eligible, but not mandatory for Google to show.

Their current solution seems to be something along the lines of: ***** Rating: 8.4/10 - 900 Reviews almost forcing two different review "views" into the same listing, which seems a little dumb from a UI perspective.

Thanks this is the kind of 2nd opinion I was looking for
