You can also use “CTRL + F” in most browsers and type in the stat you’re looking to identify. This post is organized in accordance with our leaderboards, so if you see something in the “Advanced” tab of the leaderboard that you don’t recognize, come to this page and find the matching acronym in the “Advanced” section.
