Recency is not scored — the scraper this data comes from doesn't reliably capture individual review dates, so we don't fake a signal we don't have.
How this score is calculated
score = round(rating_component × 0.7 + volume_component × 0.3)
- Rating component (70%):the operator's tracked star rating, stretched from a 3.5–5 realistic band to 0–100. Real dive-shop ratings cluster between 4.0 and 4.9 stars — mapping 0–5 straight to 0–100 would bunch every operator in the high 80s and the score would stop telling you anything.
- Volume component (30%): log-scaled review count, capped at 1,000reviews for full marks — more reviews behind a rating means more confidence it's real.
