repackaging

repackaging: fewer than half of the page's statistic and number claims are cited.

0 of 17 statistic and number claims are cited (a link, a primary-list organization, or a footnote)

No letter

No letter: a page that is not primary needs at least one checked claim for a letter, and a page of kind unknown gets none. An F needs 3 checked claims. A claim is checked when the grader tried its first link: it read the page, could not fetch it, or found that the site's robots.txt rules it out. It traces when that link led to a primary page with the number, to a page on a primary-source site where the number was not found, or to another page that has the number.

17 numeric claims on the page, 0 checked before caps

17 of 17 claims left unchecked

No fetch limit was reached on this grade; the table gives the reason each claim was not checked.

Quotes are copied from the page, 25 words or fewer; an em dash inside a quote is shown as a hyphen. The page text itself is not kept. A hop page's text was searched up to the grader's text limit, so "not found" means not found in the text read.

What every kind and letter means

Kinds

primary
the page is the origin of its own numbers (a statistical agency, a journal, a filing, or a page that states its own study and sample).
secondary
at least half of the page's statistic and number claims are cited: by a link, a footnote, a source named from the grader's primary source list, or one of two page-level rules noted on the grade page.
repackaging
fewer than half of the page's statistic and number claims are cited.
content farm
the page carries three or more content-farm marks (such as no author, no date, unrelated topics, heavy ads) and under a quarter of its numbers have a link or a footnote.
unknown
the page could not be graded (robots.txt says no, the page could not be fetched, or it had too few claims).

Letters

A
the page is primary, or at least 90% of its checked claims were found on a primary page.
B
at least 70% of checked claims were found on a primary page, or at least 90% trace.
C
at least 40% of checked claims trace.
D
at least 10% of checked claims trace, or most checked claims cite a source that could not be fetched or that the site's robots.txt rules out.
F
under 10% of checked claims trace, with 3 or more claims checked.
no letter
a page that is not primary needs at least one checked claim for a letter, and a page of kind unknown gets none. An F needs 3 checked claims.

A claim is checked when the grader tried its first link: it read the page, could not fetch it, or found that the site's robots.txt rules it out. It traces when that link led to a primary page with the number, to a page on a primary-source site where the number was not found, or to another page that has the number.

The primary source list is a fixed list in the grader: 56 sites (statistical agencies, central banks, international bodies, survey houses, journals and preprint servers), the organizations behind them, and ADP's employment report.
