@catraxx @digitaleu I literally linked to a scientific article explaining why it cannot be done in a reliable fashion. I even pointed you to the part of the article where it says so. I did not write the article, it was written by scientists a lot smarter than me and it was peer reviewed and accepted for publication in a highly respected international publication. If you claim to be smarter and has more knowledge than them, then all the more power to you - but until now, you have only made unsubstantiated claims with no documentation or references.
