About this site
Data and accuracy
Recent editions use the official final standings. Missing earlier data may be added over time. Results data belongs to the PAIO.
How medals are awarded
Medals follow each edition's rank cut-offs (typically Gold, Silver, and Bronze in roughly the top half, with Honourable Mentions below). Exact bands vary by year — see PAIO 2026.
Countries
All-time country standings are ordered by gold, then silver, then bronze. Within an edition, countries are ordered by total marks. Official and guest countries appear in separate tables. Only official team medals count toward country medal totals.
Contestant status
Official boards are split by On-site and Online when both exist. Guests and Unofficial each appear in one table for the edition.
- Official: team members; medals count for the contestant and their country.
- Guest: invited teams; medals count for the contestant, not country standings.
- Unofficial: shown for the record; not ranked for medals.
