Moderate evidence coverage

11 of 20 scored criteria link directly to a published source.

Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

Record correction. Attribution re-verification 2026-08-12: the energy density note cited a MARSTEK press release that is not among the record's sources. The recorded band is supported by the product page, which now carries the citation; no value or score changed.
