We see the following 2 groups with a statistically significant greater concentration than what we'd expect to see:In total, we found that 5,359 reviews (or 64%) are within an overrepresented word count group. These reviews have rated this product an average of 4.8, while all other reviews have rated this product an average of 4.4.

These reviewers have rated this product an average of 4.9 while reviews without substantial repetitive phrases rated this product an average of 4.7.

We discovered a total of 9 deleted Reviews for this product, with an average rating of 4.8. Even though deleted reviews don't affect the average rating, the fact that action was taken to delete reviews raises some red flags about the integrity of the reviews for the product as whole.
There are a few limitations to keep in mind regarding the Deleted Reviews test:
- We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
- We have no information on reviews that were never published in the first place.
- We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.

However, we see the following 38 days exceeding this threshold:In total, we found that 703 reviews were created on just 38 days. Although any days with a larger number of reviews than expected is suspicious, these reviews do not appear to have a significant impact on the overall rating.
