That's something that should be completely ignored. To be honest, I don't remember exactly what it was supposed to print, but I think I somehow used it to convince myself that using points where acceleration dot velocity == 0 as the endpoints for the false position algorithm would be a good way to find roots of ROC(t) - w.
