Pilou@ Yes redraw your curve! Better if it's extremities are "tangent" with their previous points!

A somewhat amphigoric proposal! But I think I get the point.

That said, the three control points at the start of Gunter's 1st curve (left) are vertically aligned, as are the last two at the end of the curve. Only the last two on the 2nd curve (right) are not aligned, but that may be his choice and I respect it.
