Possible review removal2015-02 – 2016-0875% confidence
19-month gap with rating drop from 5.0 to 4.33 (delta -0.67). The substantial gap and negative delta suggest reviews may have been removed or suppressed rather than a renovation, as a reopening would typically show rating recovery. Only 1 review recorded post-gap, consistent with review suppression or archive loss during this early period.
