Can an author still edit a published demonstration?

Mine (http://demonstrations.wolfram.com/AsymmetricSpirographs/) contains a bizarre AutoRun sequence that I just put there to illustrate a problem. It’s no good for the end user. There are also some text changes by the editors that are inappropriate/wrong.

That's a really fun demonstration.

Yes. If you'd like to make a change, you would contact the demonstrations team and just let them know.Otherwise, I would just submit your demonstration with the changed code and note that it should replace the old version for the reasons you mentioned.

Authors can always make edits to a Demonstration. They should edit the published author notebook, then send the new version to demonstrations@wolfram.com, or to me directly (edp@ ...).

To avoid jaggedness in the Autorun, PerformanceGoal -> "Quality" should be used.

There are many guideline suggestions available. I should have caught the jitteryness of this Autorun, fixable by adding an increment to the range, as in the below.

Manipulate[
 PolarPlot[
  r + (2 a - (f2percent a/50)) Sin[
     f1 (x - f1fs/180 \[Pi])] + (f2percent a/50) Sin[
     f2 (x - f2fs/180 \[Pi])], {x, 0, 2 rev \[Pi]}, 
  PlotStyle -> {Black}, PlotRange -> Automatic, 
  ImageSize -> 1.15 {400, 400}, PlotPoints -> 25, 
  PerformanceGoal -> "Quality"
  ],
 {{r, 1, Style["r", Italic]}, 1, 10, 1, Appearance -> "Labeled", ImageSize -> Tiny},
 "",
 {{a, 6, Style["a", Italic]}, 1, 10, 1, Appearance -> "Labeled", ImageSize -> Tiny},
 "",
 "frequency \!\(\*SubscriptBox[\(f\), \(1\)]\) of wave 1",
 {{f1, 0.5, ""}, 0, 6, Appearance -> "Labeled", ImageSize -> Tiny},
 "",
 "frequency \!\(\*SubscriptBox[\(f\), \(2\)]\) of wave 2",
 {{f2, 0.52, ""}, 0, 6, .001, Appearance -> "Labeled", 
  ImageSize -> Tiny},
 "",
 "cycles",
 {{rev, 12, ""}, 1, 100, Appearance -> "Labeled", ImageSize -> Tiny},
 "",
 "morph wave 1 \[Rule] 2",
 {{f2percent, 50, ""}, 0, 100, Appearance -> "Labeled", 
  ImageSize -> Tiny},
 "",
 "phase shifts",
 "wave 1",
 {{f1fs, 0, ""}, 0, 360, Appearance -> "Labeled", ImageSize -> Tiny},
 "wave 2",
 {{f2fs, 0, ""}, 0, 360, Appearance -> "Labeled", ImageSize -> Tiny},
 TrackedSymbols :> {f2},
 AutorunSequencing -> {{4, 1200}, {6, 20}, {7, 20}, {8, 20}}]

Thank you very much, Sean Clarke & Ed Pegg. I'm new at this & I don' know the ropes yet.

Ed: Thank you for the improved code. I'll be emailing you a new version.
