Here are the results of a new PubChem BioAssay AID: 2427 with 42 compounds (22 active, 2 inactive and 18 inconclusive).
AutoDock did a perfect job here giving favourable binding energy for active compounds compared to inactives. As a result, we have a prefect ROC curve here. I made the makers bigger so you can see that all actives are on a vertical x=0 line and all inactives lay on a horizontal y=1 line.
