Why Iona Anderson ranks #149 in Swimming
Iona Anderson ranks 149th among Swimming athletes on GOAT Rank and 1479th of 4013 across every sport in the index. The published GOAT Score of 81.3 is the weighted result of five verified category scores: Dominance 80, Peak 90, Longevity 66, Honours 86, Statistics 86. Those categories are normalised against the full Swimming reference universe of 289 records, not a shortlist, so the position reflects the whole sport rather than a handful of famous names.
The record covers 2021–present with 6 documented competitive seasons. The strongest single season in that series is 2024, which sets the Peak component at 90. Peak is the defining strength of the profile at 90 out of 100, and it carries 20% of the final score. The underlying career record includes olympic gold medals 1, olympic medals 2, world championship medals 2, australian titles 4.
Immediately ahead sits Nicolò Martinenghi on 81.4, a gap of 0.1 points. Directly behind is Dyana Calub on 81.2. The position moves whenever the verified record moves: new titles, new seasons or a corrected source all feed straight back into the same formula, and every change is dated on this profile.
