Non-article content types (reviews, components, corrections) typically have lower metadata coverage, which can reduce the aggregate score above.
Why doesn't the leaderboard use per-type scores? Deciding which content types count as "primary research" is subjective and varies by discipline and publisher model. The leaderboard uses Crossref's aggregate coverage to ensure a consistent, comparable baseline across all 27,000+ publishers. This per-type breakdown lets you see the full picture for any individual publisher.
