We don’t need the actual calculations, but what factors go into it would be nice to know.
Something like the ODR:
The Order Defect Rate (ODR) is a key measure of your ability to provide a good customer experience. It’s all orders with a defect (defined below) as a percentage of total orders during a given 60-day time period.
An order has a defect if it results in negative feedback, an A-to-z Guarantee claim that is not denied, or a credit card chargeback.
Note: Seller Rating is not a new thing.
Seller central used to have it but it was removed when they “Improved SS”
