Write to support@pyxl.pro about a mistake, a missing entry or anything else on the site.
Where to write
Email reaches the people who maintain the data: support@pyxl.pro. There is no contact form, so nothing you send is stored on this site.
Before you write
Each figure links the source it comes from and shows the day that source was checked, so opening it often settles a question. If the source has changed since that day, tell us which edition or version you read, and the page will be compared with it.
Reporting a mistake
Name the page, the figure you believe is wrong and, if you can, a source that gives the right value. A link to a published standard or an official page is the fastest way to a fix.
Each report is compared with its source; when it holds up, the data, the page and its date change at the same time.
Replies
We read every message about a mistake in a size or a page. Replies are in English, and a confirmed mistake is fixed on the page with its new date.
