How these pages are made

Every vendor fact comes from one data file, and each value carries its source link and the date it was read. The oldest check on any page is 2026-10-18 and the newest is 2026-10-18. A report lists any row older than 45 days so it gets re-read. We did not call any vendor, sign up for a trial or test a competitor's product; the figures are what the vendors publish. A cell reading "not stated on pages read" means the pages we read did not say, which is different from the vendor not offering it.
