Of course, it is always a pleasure to communicate with professionals in their field. However, did you consider that developers of the Catalog of Human Population, who provided this information to you, have never met any of the people from your group? Moreover, it is very likely that they have never in their lives met any person born of this date?
People request information from the Special Scientific Info-Analytical Laboratory—Catalog of Human Souls about those, who the developers of Catalog of Human Population have never met. Meaning that, unlike you, the developers are not able to observe this person, see how she/he lives and functions, talk with that person in order to find out some information, and so on.
When verification of this research was carried out in Russia in the 90s of 20th century, psychologists compared data about subjects that they received from the Catalog of Human Population with data about subjects, which they obtained using traditional psychological methods. This means that they operated in the same way as you did.
Although this approach is quite strange from the point of view of a psychologist, who practices based on Non-Traditional Psychoanalysis. In non-traditional analysis, after reception of information from the Catalog of Human Population (even if you think that you studied a person well), it is necessary to observe him/her for some time, so to speak, with new information in hand.
