The historical archive

What was checked

Each released scoresheet is checked against its season’s element values, GOE conversion, component factors and rounding. Reconstructed TES, PCS and final scores must match the published scores. Event-level checks reconcile protocol scores with the available official classifications; withdrawals and nonqualifiers remain distinct.

The source list inside each competition retains original files, source links and document fingerprints. Some official whole books have damaged or scanned text layers. Their original bytes are preserved, with separate phase documents or reviewed visual extraction supplying the verified results. Derived text never replaces the original document.

Source details to keep in mind

• Worlds 2025: separate phase protocols and classifications are verified; the whole book’s damaged character map prevents a complete automated text comparison.
• Warsaw 2024: Women and Pairs phase panel identities were not published in the recovered materials. Their seven judge positions remain unnamed. A mislabeled Pairs attachment was rejected and replaced with the official ISU final summary.
• Denis Ten 2024: missing PDF character maps were recovered from the embedded glyphs. The original PDF remains unchanged; rendered pages and all scores were checked.
• Ankara 2024, Junior Men short program: the original J1 column is entirely blank. It stays blank and is excluded from averages.
• Golden Spin 2023: Men’s and Pairs’ free-skating panel lists were not published in the recovered source. Their judge slots remain unnamed; the scoring protocols are verified.
• Denis Ten 2023: all six Senior phase protocols, classifications and panel lists were recovered from archived copies of the official site. The whole-event book remains unavailable. Officials printed only as “ISU” retain unknown federation codes.
• Golden Spin 2022: an organizer’s Men’s final summary has a one-point error for Semen Daniliants. The phase results and the ISU final summary agree on 139.79; both versions and the correction evidence are retained.
• NHK Trophy and Junior Grand Prix Japan 2023: two published base values differ by one cent from the usual order of repetition and bonus rounding. These reviewed source exceptions retain the printed 3.27 value; other protocols keep their original convention.
• Denis Ten and Graz 2022: original official documents were recovered from dated web archives after the organizer links stopped responding.
• World Team Trophy and Youth Olympic team segments have separate records. These do not create an individual combined competition result or World Standings points.

2018–19 to 2021–22

94 of 94 targeted held-result archives are represented in 103 catalog records: 11,295 performances and 98,097 elements. Each score uses its season’s five program components, original calls, deductions and Scale of Values.

The scope covers championships, Olympics and Youth Olympics, Grand Prix and Junior Grand Prix including Finals, Challenger Series, World Team Trophy, and other events explicitly listed at ISU level. Senior and Junior records and team phases are kept separate. Novice, interclub and accompanying non-Senior Challenger categories are excluded. “Represented” does not mean every category or official identity was recoverable.
