How we verify the data
- Every fact has a source URL stored in the database β federation scorecards, Wikipedia articles, podcast transcripts, sponsor announcements. No anonymous claims.
- A nightly automated sanity check verifies anchor truths: known Ms. Olympia win counts, all-time records, structural invariants (one #1 per division, no biological out-of-bounds values). If any anchor fails, new data is not promoted to the public site until the issue is fixed.
- Derived numbers (Iron Score, Muscle Dominance heatmap) carry a methodology link explaining the formula and inputs. They are clearly labeled as derived.
- Reader corrections are processed within 48 hours and logged publicly. Use the form below.

We do not claim this dataset is complete or error-free β no public sports dataset is. We do not claim affiliation with the IFBB Pro League, NPC, NABBA, WFF, WNBF, OCB, PNBA, or any federation. We do not publish AI-generated photographs of real athletes. Iron Cards are stylized identity graphics built from public data, not portraits.
