Corrections and source questions
For an article correction, include the page URL, the statement you think is incorrect, and a supporting reference if available. For a calculator issue, include the units, inputs, displayed result, and expected result. Danish Javaid checks reports against the published sources and reproduces calculation issues before correcting confirmed errors. The editorial policy explains how corrections and updates are handled.
A detailed report makes it easier to investigate. General inquiries normally receive a reply within the target above; checking a calculation or reference may take longer. Please avoid sending private building documents or sensitive personal information.
