I had many Live Chat and email exchanges with support which resulted in zero meaningful information about this less than 2 weeks ago. First I got many, many bluff answers in Live Chat - absolutely meaningless bullspit - the answers simply rephrased the questions
I then tried email and the most "credible" answer I got was that the whole area was an old out of date function which now has no meaning whatsoever - but I can see that the data is still current with new results being added every day.
