Southern California Swimming Boys 10 & under - 50 M Back

These rankings show the swimmers' placement within their Local Swimming Committee (LSC).
They are based on the swimmer's personal best, their current age category, and team; and are calculated from all the meets results.
For each swimmer, you can find the swimmer's ranking, their best time, the corresponding time standard, as well as how much faster the swimmer needs to be to reach the next level. The last columns provide information about the event they achieved this personal best.
