Hi Art
I just want to confirm if you are seeing incomplete, duplicate, inconsistent listings fall off but not see the score increase? If those changes are not picked up, this would explain the score from not moving. Picking up those changes will depend if the service we are querying has updated their API. Most of the services we are searching will host two databases, one which can be accessed live directly on the page. If our tool is not picking up the changes, then you would need to report those services to let them know their API is not reflecting the updates.
If they are being picked up and the score is not moving, I am researching this with our engineering team and will let you know what I find out.
