I see. May I suggest we add a separate column instead? ``` Output For the average function, a single value for simple silhouette score is returned. For the per-point function, the output table contains the following columns: pid INTEGER. Point ID. centroid_id INTEGER. The cluster that the point is assigned to. neighbor_centroid_id INTEGER. The next closest cluster to the one that the point is assigned to. simple_silhouette DOUBLE PRECISION. Simplified silhouette score for the point. ```
