Where the data comes from
TourneyRadar runs an automated scraper against public tournament listing sources, geocodes each event, and stores the result. It is not manually curated tournament-by-tournament -- freshness and coverage both depend on the scraper running cleanly, which is why scraper health has its own status page.
Refresh cadence
The scraper runs on a recurring schedule (currently every 6 hours via a GitHub Actions cron job) and only touches upcoming, published events. If a tournament looks stale or wrong, it likely has not been re-scraped since the organizer last updated it at the source.
What "FIDE-rated" means here
A tournament is marked FIDE-rated when the source listing itself reports it as FIDE-rated. TourneyRadar does not independently verify FIDE-rating status with FIDE -- always confirm on the organizer's own page before assuming a result will be rated.
Open source, open data
The scraper and the schema are public in the GitHub repo. If you spot a data quality issue, open an issue rather than guessing at a fix -- someone else may already be tracking the same one.
