Thanks, please provide the link.

Would something like "The value of 2.01‰ can be calculated from
the maximum deviation of 1%" be sufficient? There is no easy way
the calculation itself can be explained in a few sentences, that is why
I referenced the document. When I have a link, I can also reference
the document directly in the code.
