Yes, and if you paid attention, or read that page carefully, then you would see that these techniques are not presented on that page (nor any of the other pages you cited.).

You would want to affect them globally to achieve a "house style". Or, simply choose a starting point that fixes most of the issues with the curves, before proceeding to the tedious work of one-at-a-time techniques. Plus, while you can achieve similar results using the different techniques,these different approaches are not comparable: one is manipulating differences in control points from the default algorithm, the other is affecting the values used in the underlying algorithm itself. > And is it sensible to try to teach: > > (spanner-id .
