Sources and how they are ranked

Every figure carries the document it came from and a tier describing how close that document sits to the manufacturer. The tier is what decides which value leads when sources disagree, and what a source is allowed to contribute at all.

Tier 1ManufacturerDatasheets, spec pages, manuals, press releases, official documentation.
Tier 2Authorised distributor or integratorCatalogues and product pages from companies selling the machine on the manufacturer’s behalf.
Tier 3Trade press and reviewsMay contribute a figure where no tier 1 or 2 value exists. Contradicting one marks the figure disputed rather than replacing it.
Tier 4CommunityForums, video, comments. Never writes a specification — only points at things worth reading.

Facts, not prose

A payload figure is not copyrightable and is aggregated freely from wherever it was published. The sentences around it belong to whoever wrote them: source documents are stored so a figure can be checked against what it came from, and never republished. Articles are linked, with a one-line summary, never reproduced.
