What to write about

Corrections: if a figure on a page disagrees with its cited official source, send the page URL and the source link — corrections are our highest-priority mail.
Calculator bugs: method, inputs, expected vs shown values. The engine has a test suite, but real users beat synthetic tests.
Source disputes: a maker's guide changed or you publish an official recipe we don't reflect — include the link.
Topic requests: methods or gear categories you'd like covered next.

We read everything and usually reply within a few business days. We do not accept guest posts, sponsored recipes, or "calculate for my brand" requests.
