Hello and thanks for your work on PreferentialBot! Just wanted to raise an edit on Institute of Mathematics and Statistics, University of São Paulo (Q10302895). For students count (P2196)we have two values, one for undergraduate student (Q21094885) and other for graduate student (Q18245166). Both have the same point in time (P585). The bot picked one of the two to mark as preferred but I'm not sure this is the best solution. I'd probably keep both ranks the same. Thanks!
