Above are the fastest times that Sean Kohno has achieved in his swimming career. For each event, you can find Sean's best time, the corresponding time standard, as well as how much faster Sean needs to be to reach the next level. The last columns provide Sean rankings at the team and LSC levels. These rankings are based on the Sean's personal best, his current age category, and team; and are calculated from all the meets results.
