How do you define "smooth"?  With Bézier splines, it means that the 
tangents at the anchors points are collinear. By construction, your 
algorithm makes them not so, and it just strives to reduce the angle by 
multiple iterations. Do you have an estimation of how many iterations 
you need before the angles are no longer visible?
