How we rank
The WeedDispos Score is a 0–100 composite built only from data we already store for each licensed shop: review rating (Bayesian-adjusted so a 5.0 from three reviews cannot outrank a 4.8 from two thousand), review volume on a log scale, how recent those reviews are, listing completeness, verified status, whether we have a live product menu, and photo coverage. Signals we do not have for a store are dropped and the remaining weights are re-normalized, so nothing is penalized for missing third-party data. Scores refresh nightly. Ranking is never for sale.
