Each source is averaged first, then sources are weighted by reliability: audits, lab tests and verified-buyer platforms count most, rating organisations and expert reviewers less, brand-run reviews and community opinion least. Review scores also weigh by how many reviews stand behind them, and anything older than three years fades.
