Corrections

Last updated: 2026-08-02

If something on this site is wrong — a number, a formula, a claim in an article — we want to know, and we fix it at the source.

How to report an error

Email contact@brobrogo.com with the page address and what is incorrect. A pointer to an authoritative source helps, but is not required.

What happens next

We check the report against authoritative sources or recompute the result. A confirmed error is corrected on the page itself, and the page's last-updated date moves with the fix. Changes to how a tool behaves are listed on the changelog.

Our standard

A wrong answer on a calculator is worse than no answer. When we cannot verify a claim, we remove or qualify it rather than leave it standing.
