Kirill, I'm with Validity. I can tell you we are intent on producing quality scores and if there is erroneous data feeding the model we are happy to take a look at it. In the case of "bad" input, we'd look at issuing corrective measures. You can open a ticket at datahelp at validity dot com if you'd like to pursue any further.
