If it's not used at all, why does the FAQ state, "In SpamAssassin 3.x, the scores are assigned using a neural network trained with error back propagation?"

Let me make sure I understand: the Bayes database is the primary form of customization done by default, although the underlying pre-trained neural net is the primary method for weighting scores? If you just run spamassassin with the default settings, is it not using the neural net to weight the various test scores? Or is the neural net itself its own separate test? Thank you for the information, Gabriel
