How a location score is calculated
Each rating uses the five weights above. A location’s score averages eligible published guest ratings within the selected period, then rounds the result. The directory shows the last 30 days and the number of ratings. With no ratings in that period, we show “Not yet rated.”
From your tap to a number
On the website, rating is deliberately quick: you pick one overall verdict — Pristine (100), Needs Help (50) or S.O.S. (0) — and that value is applied to all five categories, then combined with the weights above. Because every category carries the same value, the weighted result equals the verdict you picked: a Needs Help tap scores 50 × 40% + 50 × 20% + 50 × 15% + 50 × 15% + 50 × 10% = 50. In the Pristine Potty app you can score each of the five categories individually, and the same weights combine them. Website and app ratings are pooled into the same location score — neither counts more than the other.
A worked example
An app guest scores one restroom Cleanliness 90, Functionality 80, Supplies 60, Odor 100 and Safety 80. Weighted: 90 × 40% + 80 × 20% + 60 × 15% + 100 × 15% + 80 × 10% = 36 + 16 + 9 + 15 + 8 = 84. If that restaurant’s other ratings in the last 30 days are 100 and 50, its location score is the average — (100 + 84 + 50) ÷ 3 = 78 — shown rounded, in the Needs Help tier (70–89).
The optional details
The rating form also offers seven optional “Tell us more” answers — soap dispenser, paper towels, toilet paper, hand dryer, changing station, lighting and floors. They are saved with your rating as extra detail and line up with the things owners watch most closely (the supplies items with Supplies, the hand dryer and changing station with Functionality, lighting with Safety, floors with Cleanliness), but they never enter the weighted score — only the five categories above do. Skip any or all of them freely: a skipped answer records nothing for that item and can never lower a score.
Participation is separate from performance
A directory listing means the restaurant has opted in and its profile has been approved. It is not an endorsement of its score. A Pristine tier reflects guest feedback; it is not an inspection, accessibility audit or food-safety certification.
Useful feedback is honest feedback
Rate a place you actually visited. Avoid personal information in comments. One web rating per signed-in guest, per restaurant, per UTC day helps reduce duplicates. Rewards do not require a positive rating.
