Athlete Selection Criteria: Base Time Proximity Standard

On August 12, 2022, the GSF unanimously adopted the BASE TIME PROXIMITY STANDARD to calculate the times and ranking of athletes to be selected for attendance at international off-island competitions, with the exception of the Olympic Games. Sometimes called the “Percentage of Time Standard,” the criteria is used by major swim federations to establish a uniform way to compare times and rank athletes across different events. 

The standard compares the difference between a swim athlete’s time in an individual event to the “B” time standard (ie, the “Base Time”) for that same event as established by a competition’s meet organizers. The formula divides the athlete’s time by the Base Time, and the quotient is converted to a percentage. Athletes will be ranked in order of their percentages, with the highest ranking athlete being the one whose swim time is closest to the Base Time (or “1”).

For the Olympic Games, the qualification and selection criteria shall be that as established by FINA. For universality placement, and at GSF, GNOC, and FINA’s discretion, only the male and female athlete who has achieved the highest FINA Points Table score in any individual Olympic event, as achieved at a FINA-approved qualification event during the qualification period, shall be entered.
