Scoring Formula

Raw scores for each KPI are normalized to a 0-100 scale using min-max normalization across the evaluation universe. The overall integrity score is calculated as the weighted sum of normalized KPI scores, using the category-specific weight distribution shown above. Platforms are ranked by descending overall score within each category and across the full index.

Overall Score = Σ (KPIi × Weighti) for i = 1 to 12
where KPIi = (rawi − mini) / (maxi − mini) × 100
