Why Kosuke Hagino ranks #77 in Swimming

Kosuke Hagino ranks 77th among Swimming athletes on GOAT Rank and 777th of 2289 across every sport in the index. The published GOAT Score of 82.3 is the weighted result of five verified category scores: Dominance 82, Peak 90, Longevity 74, Honours 82, Statistics 84. 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 2012–2021 with 10 documented competitive seasons. The strongest single season in that series is 2014, 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 4, world championship golds 1, asian games golds 11.

Immediately ahead sits Amy Van Dyken on 82.4, a gap of 0.1 points. Directly behind is Thomas Ceccon on 82.2. 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.
