Please Help me...For loose line fixer

Question

Hi,
I just want to try a script for fixing loose lines automatically. My concept is,
1) Finding the wrod space width.
2) Depending on the width value, fix desired width value. I know it may vary for each character and fonts.
3) If finding any over widthed space inside the para, i need to give tracking from value -1 to -10 untill we reached desired width. If not possible retain to zero tracking(original state). We don't need to check this for single line para, so just skip that.
My client SOP:
1) H&J values should not changes.
2) Single line composer alone used
3) Single line tracking not used.
4) Positive tracking not allowed
5) Tracking value should between -1 to -10.
Is it possible?
Thanks in Advance.

Hi ,
My friend gave me a little script to find space width of paragraph.
//Setting preferences to point and
//set page rulers to pageOrigin
var myDoc = app.activeDocument;
myDoc.viewPreferences.horizontalMeasurementUnits = MeasurementUnits.points;
myDoc.viewPreferences.verticalMeasurementUnits = MeasurementUnits.points;
myDoc.viewPreferences.rulerOrigin = RulerOrigin.PAGE_ORIGIN;
myDoc.zeroPoint = [0, 0];
var docStories = myDoc.stories;
for (var st=0; st<docStories.length; st++){
    var paras = docStories[st].paragraphs;
    ClearGrepPreferences();
    for (var p=0; p<paras.length; p++){
        if (paras[p].lines.length>1){
            app.findGrepPreferences.findWhat = " ";//Find All spaces in current paragraph
            var spaces = paras[p].findGrep();
            if (spaces.length>0){
                spaceWidth = spaces[0].endHorizontalOffset-spaces[0].horizontalOffset;//end position - start position gives the width of the space character
                alert("Paragraph "+(p+1)+" Space Width = "+spaceWidth);
            }//End of if loop lines >1
        }//End  of "p" for loop
    }//End of stories for loop
function ClearGrepPreferences(){
    app.findGrepPreferences = NothingEnum.NOTHING;
    app.changeGrepPreferences = NothingEnum.NOTHING;
    app.findTextPreferences = NothingEnum.NOTHING
    app.changeTextPreferences = NothingEnum.NOTHING
From this script, i want to find the average space width of entire document (it actually find the space of each para). It will saved in the variable  spaceWidth. Then the script ask user for giving a desired space width. Let say, userSpace. Then it will compare the userSpace with   spaceWidth. If the space Width is more than userSpace value,  then allow tracking from -1 to -10 using FOR loop to get desired value. If it will not get desired then retain the para tracking as zero and skip to next para.
Am i get any help from this point?
Advance thanks
