Performance points are calculated to provide a basis for comparison of results between swimmers in different events. A common formula is used for each calculation with different base times utilized on the basis of the organization type. Performance scores are only calculated from complete result files.
Each point system is established with a base time of 1000 points. This time varies according to the organization and is based on the appropriate record. The current base times used include the following:
- World Records (utilized for global rankings, United States club swimmers)
- National Age Group Records (utilized for United States swimmers aged 18 & under).
Base times are established for individual and relay events in all relevant courses.
Calculating Individual Points
Points are assigned to each swim utilizing the following formula:
Calculating Performance Scores
A swimmer's Performance Score is calculated using a weighted average of their four best events (regardless of course) in a given season. Here is an example:
|Event||Base Time||Swimmer's Time||Points||Weight||Score|
Swimmers With Fewer than Four Times
If a swimmer has fewer than four times in a given season we calculate a Proxy score for third and fourth events. These scores are calculated on a curve based on the performances of 567,000 swimmers between 2016-19. Generally speaking, a proxy score for a swimmer's third event will be 13-33% lower than their best event while a proxy score for their fourth event will be 18-50% lower.
