I'm glad you asked. The new "Rating" feature shows you where you stand in comparison to other contributors to Adobe Stock. you can check this based on lifetime stats for your overall standing or based on weekly stats to see where you stand in the short term. If you see you rating improve (smaller number) weekly you know you are on the right track and improving in your personal account above the average of other contributors.
Another portal update that may have gone unnoticed is a direct link to your statistics from the Dashboard page. This link is in the upper right corner of the page and bypasses the contributor of the week feature which is the default landing page for the Insights tab.
