Rankings

Updated May 2026

Rankings should be useful without pretending to be more official than they are. ProTriStats separates official imported rankings from derived fan-analysis rankings.

Operating principles
  • Official rankings and ProTriStats rankings live in separate tabs and use different labels.
  • Every ranking needs a date, source or methodology note, eligible race count and completeness state.
  • Derived rankings should explain "why ranked here" in terms of recent results, points, split ranks or consistency.
  • Incomplete official snapshots should show a warning or stay hidden until they pass a completeness threshold.

Official rankings

Official rankings include PTO World, T100, IRONMAN Pro Series, World Triathlon and other organizer-published standings when imported. These should preserve the source position, points, ranking date and source URL.

If ProTriStats has only a partial snapshot, the UI should say so clearly. A partial official ranking presented as complete is worse than no ranking table.

ProTriStats rankings

Derived rankings are fan-analysis tools. The useful set includes current form, season performance, 70.3, full-distance, swim, bike, run and consistency rankings.

A derived ranking should be explainable from visible evidence: recent eligible races, best points performances, split ranks, finish positions, DNFs and field strength where available.

Completeness and eligibility

Eligibility should be strict enough to prevent one-off outliers from dominating but simple enough for a casual fan to understand. For example, a form ranking can require a minimum number of recent finished starts.

When an athlete is missing because they lack eligible results, the page should make that reason discoverable instead of implying they are ranked poorly.

Limitations
  • - Derived discipline rankings depend on valid split data; races without splits should not be guessed.
  • - Different distances and course types make raw time comparisons risky.
  • - A high consistency score can favor athletes who race often unless eligibility and race strength are handled carefully.
What users should expect
  • - Keep official and derived rankings visually and semantically separate.
  • - Show methodology snippets beside ranking tables rather than burying them on this page only.
  • - Expose enough row-level evidence for users to sanity-check surprising rankings.
