https://community.usms.org/events/f/usms-national-championship-international-events/26260/2010-worlds-sweden-qualifying-timesDoes anyone know if short course converted times are valid for qualification purposes? From the meet information, it seems like there&#39;s not an issue unless you don&#39;t actually swim a qualifying time at Worlds.

It would too much time for the host to check to see if valid times have been entered. Therefore, they just don&#39;t list your time in the results if it is slower than the qualifying time.<div style="clear:both;"></div>
