How does deleting a fighter's highest ranking improve the page? edit

We have a source saying that Turner's ranking was #10 in October 2022 and that fact and the source have been deleted by several IP editors and now by @KyleBYerrick. While it's certainly fine to update his current ranking now that he's dropped to #12, what's going to be important in WP:TENYEARS is the top rank he attained, which is what we do for other competitive sports with rankings. In the long run, everyone retires and is dead. We should WP:PRESERVE the top rank achieved rather than delete that information along with the reference. BBQboffin (talk) 01:00, 13 July 2023 (UTC)Reply
