The UFC record books

Where the numbers come from. The official UFC statistics record — the same tape every bout page on this site is built from. Elapsed fight time is derived from the round a bout ended in, the clock at that moment and how long each round of that format was booked for, so an open-format bout from the 1990s is measured by its real length rather than as though every round were five minutes.
Where a division page exists and where it does not. A per-division record only gets its own page where the division has at least 25 qualifying bouts AND at least 25 distinct values to rank them by. The second condition is the one that matters: 307 bouts have gone the full twenty-five minutes and are exactly tied, so a per-division “longest fights” page would be a hundred rows reading the same number. The build decides that from the data every time it runs.
