Corrections to a measurement, a rule or a date are the most valuable messages this site can receive — every rule carries its source and verification date precisely so it can be challenged.

Reporting a wrong number

If a ratio, threshold or rule on this site disagrees with your own computation, the fastest route is the methodology page: the formula, the thresholds and the hand-computed vector table are all published there. A report that names the pair and your computed value will always be checked against that record first — if the site is wrong, the record is corrected and the correction noted.
