Why there's no Clarity Score yet

The Clarity Score is computed from full financial filing history. International Prader-Willi Syndrome Organisation is on the official register but outside the detailed-filing group we currently score (or awaiting its first filings), so we show its official register record instead of a rating. Its score appears automatically once enough filing data exists — never by payment. How scoring works
