Hello Julio, Thanks for your feedback! The Elbow method may produce plots with concavity changing from one point to a next. It means that some points must be removed from consideration, and my method takes care of this. In addition the math is adapted for clustering procedure and much simpler. This helps with efficiency and maintenance. Best regards, Mya
