Yes, thanks. It does, but it opened up another set of questions. The issue was not just the smooth curve, it was what the higher precision and accuracy curves were, what they mean if anything and whether they are telling me things that the smooth curve was not. This point is a bit clearer in the attachment above in the last figure of the set of four.
I would have replied to the previous post you commented on, but that thread was closed for "drifting" off topic. Thanks for getting back on this.
