What to send

Calculator problems: the page URL, the values you entered, and what you expected versus what you saw.
Formula or threshold corrections: the page, the value you believe is wrong, and the source it contradicts — a service manual, manufacturer spec, or measured data. Every formula and threshold on this site is listed with its source on the methodology page precisely so corrections can be checked; verified corrections are fixed promptly.
Business inquiries: advertising, partnerships, or press — the same address.
