In order for any of us to try to help you will need to elaborate a bit more. What part is inaccurate? Why do you think it's not accurate? Have you read through all of the info etsy provides about the program? https://help.etsy.com/hc/en-us/articles/4403058372503-How-to-Become-a-Star-Seller?segment=selling
Also, just FYI- it's just us sellers here who can try to help. I know etsy help center tells you to post in this forum for issues with star seller calculations but etsy changed this to a peer to peer support forum a while ago so you aren't actually reaching etsy when you post here. If you need help from etsy support you will need to contact etsy support directly through the support ticket system.
