Okay.  This is the script GUI.  Here's a basic explanation of the options.

• Select Morph(s) listbox:  The script works on the current deformed shape of the selected actor.  By default, the shape is restored toward the base geometry.  However, you can select any combination of morphs in the listbox to modify the shape toward which it will be smoothed.  So listbox selections essentially morph the base shape, for the purpose of the script's corrections.

Note that if you select the currently active morph(s) - assuming they're at 1.0 value - in the listbox, the script won't do much of anything because it's trying to move the current shape back toward itself.

• Screen matched verts checkbox:  If checked, the script will stop processing a vertex once that vertex's distance from its neighbors reaches the "Threshold" value.  This may create faster processing times, by avoiding potentially redundant processing of a vertex which is already as close as you'd like to a corrected position.

• Threshold entry box: This is the distance value which will be used by screening with "Screened matched verts", as well as the "Screen High"/"Screen Low" radio buttons.

• Screen High/Screen Low radio buttons:  Screen High will exclude vertices whose distance is greater than or equal to the threshold value.  Screen Low will exclude vertices whose distance is less than or equal to the threshold value.  ("Distance" is distance from neighbor vertices.)

• Max Repititions entry box: If "Screen matched verts" is checked, the script will keep repeating its processing loop on the mesh until all vertices are screened out or it reaches the maximum number of repitiions, defined here.  If "Screen matched verts" is unchecked, the script will continue processing until it has run the maximum number of repititions.  (Which is either not a word, or Firefox's spell-checker doesn't know it is.  Hmm.)

So with screening, keep the max value high enough for the script to potentially reach the point where it can have screened out all vertices.  It probably won't run anywhere near 1000 reps on an mesh, with screening. The default value is simply intended to be high.  Without screening, the script will run all repititions, so it's probably best to keep this value lower.  I've never used more than 10, usually 4, without screening.  Theoretically the script could keep running for a long time, if you give it a max which is too high, without screening.

• Use X/Use Y/Use Z checkboxes: Processing can exclude any of the three dimensions of a coordinate's location from all vertices while processing.  If you uncheck all three, the script will screen everything and do nothing.
