Reference values derived from established, international senior elite swimmers pertain to the 100m Freestyle event, unless otherwise indicated, while those obtained from Dutch youth swimmers on track to reach the elite level cover various events. Swim performance is indicated as the season best time relative to the prevailing World Record (WR). Within season progression is indicated as the percentage change a swimmer has moved towards the prevailing WR.
