How loved this beach is — saves, visits, star reviews & Google popularity
Star ratings and Google reviews (our stand-in for web popularity) set the base score; saves and visits from Sandy Pup users then add a boost on top — up to 30 points, growing as more people engage — so community love can lift a beach, never sink it. Every count uses a diminishing-returns curve (the first few matter most), and signals with no data yet are skipped — never counted against the beach.
