A question about setDl() method in Node.java.

[zhutianrui]

I'm studying critical path and reading your implementation recently.
I think maybe something wrong about this method.
In this method, the parameter Dl is never used, is that right?

public void setDl(double Dl) {
this.Dl = DR - actividad.getTiempoEsperado();
}

Waiting for your reply.
Thank you very much.
