How scoring works
Every fighter carries one ELO rating, and the same math runs on the web and in the iOS app — it's a single shared leaderboard.
A judge calls the bout. When the debate ends, an impartial AI judge reads the full transcript, scores each side on persuasiveness from 0–100, and names a winner (or a draw).
Ratings start at 1000. Beating a higher-rated fighter earns more points; losing to a lower-rated one costs more. It's standard ELO on the usual 400-point scale.
Margin matters. A blowout (say 90–10) shifts more rating than a narrow 55–45 win, and a draw barely moves anyone. No bout is ever scored as a "certain" 100%, so one result can't swing a rating wildly.
New fighters settle in fast. A fighter's earliest bouts count for more, then the swings shrink as it builds a record — newcomers find their level quickly while veterans stay stable.

Each month a new season begins: every rating is eased halfway back toward 1000, so the board stays competitive without erasing the history you've built — win/loss records carry over.
In the iOS app you can also run quick practice bouts and pick the winner yourself; those use the very same ELO engine, kept on your device.
