Contact & Corrections
We welcome evidence-based corrections to the wiki's data and calculator assumptions.
Report a correction
The fastest way to help us verify a change.
Email [email protected] with the affected page URL, the value or claim in question, and a link or screenshot of the supporting source.
Reports that distinguish official evidence from community observations are especially useful. We will label unresolved conflicts instead of silently replacing one unverified claim with another.
