Hi Burr, yes I think that last description you put in (go back later and adjust with show points to refine) is a good idea.

After a bit of practice you can start to get used to the way the control points work, you kind of place them slightly to the outside of where you want the curve to go, since the curve is kind of shrunken and smoothed down from that control point hull.

After you practice it for a bit, it gets easier to trace things.
