Weighted rating combines star average and review volume, so a 5.0 with 30 reviews doesn't outrank a 4.7 with 2,000. Range evidence required.
Weighted rating: WR = (v·R + 150·4.5) / (v + 150), where v = Google review count and R = Google rating. Requires ≥ 25 reviews and at least one active range row with lane_count or length_yards.
