How to read the status badges
- Confirmed Read on the maker's own page, spec sheet, docs or press release as a stated value.
- Claimed Stated by the maker as a target, preliminary figure, “up to” value or performance claim.
- Estimated Derived by us or taken from a third party. Not maker data.
- Unverified No maker primary source checked yet. Treat as unconfirmed.
- Not published The maker does not publish this value.
Every Confirmed, Claimed or Estimated value links to its source and shows the date it was checked.
