Help - Athlete Analysis

The athletes swim times history is converted into FINA points (2024) and plotted in relation to the age of the swimmer. Note that the swimmer's birthday is normalized to the 1st of January.
This has two benefits:

when comparing two swimmers of the same age group, the competitions dates are aligned
the competitions are aligned to the nation's LCM season

Short and long course times are shown in the same plot:

SCM Short Course Meters (25 m): circles
LCM Long Course Meters (50 m): squares

NIVEAU Curves

These curves are an approximation of the Rudolph point table (2024).

Rudolph points are a measure of the simmers age-appropriate performance. They base on the analysis of swim results of German swimmers and were developed by Dr. Klaus Rudolph.

[0] Rudolph points: Beginner
]0-5] Rudolph points: Intermediate
]5-10] Rudolph points: Local level
]10-15] Rudolph points: Regional level
]15-20] Rudolph points: National level

Note that swimmers reaching high Rudolph points at an early age does not necessarily mean that they become the future top athletes.

RANKEQUIVALENT Curve

This curve approximates the FINA points needed to reach a specific rank. It is based on results of season 2016-2019 top times LCM of 10-19 years old swimmers. Supported nations:
BEL, CAN, EST, FAR, LTU, NED, POL, POR, SUI, SVK, SRB

Overall Progress - 650 FINA Percentiles

The 650 FINA percentiles base on national swimming result data. Each season, the swimmer's top 3 FINA results are averaged. LCM- and SCM seasons are considered individually.
60% of the athletes who reach at least 650 FINA points in their career pass the inner band. The outer band covers 90% of those athletes.
Supported nations:
BEL, CAN, EST, FAR, LTU, NED, POL, POR, SUI, SVK, SRB

Help - Nation/Region/Club Analysis

The nation analysis is based on the athletes individual top 3 seasonal results. The results are converted into FINA 2024 points:

SCM: The seasonal top 3 SCM FINA points are averaged.
LCM: The seasonal top 3 LCM FINA points are averaged.
Mixed: The seasonal top 3 LCM or SCM FINA points are averaged.

Landscape Diagram

Gives an overview of the individual club position within the 'Landscape'. The Y axis reflects the top performance of the club whereas the X axis shows the broad performance.

Progress Diagram

Shows the club/region/nation progress during the last decade.

Performance Distribution Diagram

The diagram shows the performance distribution across the age groups. The levels are derived from Rudolph points:

[0] Rudolph points: Beginner
]0-5] Rudolph points: Intermediate
]5-10] Rudolph points: Local level
]10-15] Rudolph points: Regional level
]15-20] Rudolph points: National level

Rudolph points calculation:

Season 2004-2008: are based on Rudolph/FINA table 2008.
Season 2009-today: are based on seasonal Rudolph/FINA tables.

Rudolph points are only defined for LCM. However, Rudolph points for SCM are derived via FINA points:
time_scm→FINA→time_lcm→Rudolph

Athlete Numbers Diagram

Shows the athlete numbers on the level of club/region/nation. The following cases are considered:

same: The athlete stayed in the same club.
from inactive: The athlete started participating in competitions.
from extern: The athlete came from another club.
to inactive: The athlete stopped participating in competitions.
to extern: The athlete moved to another club.
