Personal Best times (PBs) can be set at galas, open meets, and in some instances, time-trials.  They can only be taken from relay events if the swimmer was first in the relay and the time was recorded electronically.

County, Regional and National Championships Qualifying Times can only be set at ASA licensed open meets, such as the County Championships.  Swimmers should keep a record of their pb's, but can check up to date times from licenced meets via the ASA website

Short course PBs are recorded for each swimmer on a database which is updated after each competition (galas and open meets).  This record is held so that coaches have up to date information per gender and age group, and to select teams for team events.
