1. I need to calculate the Average appointments per patient YTD. How do I export a list of unique patients who have scheduled an appointment YTD 2025 so I can divide it by the # of appointments YTD? 2. I need to calculate: Patient retention rate Percentage returning after 3/6/12 months Where is the report for this? If there's no report, how could i filter the data for total number of new patients after 3 months still booking divided by total number of new patients after 3 months? etc
