This is a count, not a forecast. Every number Sardine publishes is logged and scored against the settled Kalshi result, in public: the running scorecard is at the record, and every row behind this page is in the raw CSV (sardine_history_btc_hourly.csv, CC BY 4.0). Sample sizes count distinct settled windows, never strike-rows. Rebuilt daily from the same files.
