How an error is handled

When an error affects a result or recommendation, pause the affected function or recommendation, reproduce the issue and verify the correction. Publish an explanation when a material change alters the original guidance.

Review dates mean review

Do not renew a source review date because a scheduled job ran. Rechecking a URL’s availability does not confirm the accuracy of its measurements or conclusions.

Correction channel

Report errors to thoopring@gmail.com with the page, the values you entered and the reference you compared against. The operator, MinSoo Kim, reviews reports and records material corrections on the affected page.
