What's the basis for Sherlok's weekly queues?

Sherlok’s proprietary AI monitors your entire loan book, using over 150 data points to predict which clients have the highest churn risk and adds them to the queue for repricing as a priority. With the highest risk first and lowest last on a weekly basis, always on a Friday evening. These said data points include but are not limited to, the estimated current rate, number of people on the loan, is there a guarantor on the loan, are they a PAYG client, etc.
