Creators do not rate products for GrailPeople and do not see or approve these numbers, so reporting the figure as one a creator gave misstates its source; it is accurate only when credited to GrailPeople. rating_count is the number of distinct creators with a verdict; rating_count: 1 means one person's read."}}
