Above are the fastest times that Emma Bui has achieved in her swimming career. For each event, you can find Emma's best time, the corresponding time standard, as well as how much faster Emma needs to be to reach the next level.

These rankings are based on the Emma's personal best, her current age category, and team; and are calculated from all the meets results.
