Hello, I'm Bharel. I noticed that you added or changed content in an article, Elo rating system, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Bar Harel (talk) 17:45, 7 February 2023 (UTC)
