Shot in the dark... project due in 36 hours. help?

Question

Hi everyone. I am posting this here because I have had no luck with any other program or anyone I've been able to ask (a handful of computer science students). What I am trying to do is a fairly simple operation that I would really really like to have done for my presentation friday morning. If anyone would be able to write a script, point me to a similar script, or give me a head start/ a sample script to start working with I would immensely appreciative; I don't know of any way to repay any of you but if I can find a way I will do it. My problem:
I have 5 lines. They are exactly the same line, the same x,y coordinates; they entirely overlap each other. Their only difference is that their stroke weights vary. What I am looking to do is basically find the average stroke width of these lines. Ideally the output would be in a new line with those same x,y coordinates with the new stroke weight. A text output, any output of any kind would be perfect.
I have attached a pdf visually explaining what I am trying to do to this thread.
Again, if anyone can help me in any way, I would be forever grateful. Thank you
Nick
Edit: Random side note: Today is my birthday, this would honestly be the best present I get all day!

Answer 1

literally, perfect. i wish i could give you more points!
edit: just so you have it, here is the final script. I needed to change a couple things but i figured it out myself!:
var doc = app.activeDocument;
var sel = (doc.selection.length > 0) ? doc.selection : doc.pathItems;
//init array to hold our lines
var myLines = [];
var lowestYCoord = null;
//init the variable that will hold our reference line(the other lines have to have similar properties to this one)
var refLine = null;
//loop through the document to find pathitems
for(j = sel.length - 1; j >= 0; j--) {
   if(sel[j].typename == "PathItem"){
          if(getConstructionPoints(sel[j]) == '') {    
                  lowestYCoord = ( lowestYCoord == null) ?  sel[j].top :  lowestYCoord;
                  lowestYCoord = ( lowestYCoord > sel[j].top) ? sel[j].top : lowestYCoord;
                  if(refLine == null) { refLine = sel[j]; }
                  myLines.push(sel[j]);
//let's loop through our lines if we have any
if(myLines.length > 0) {
    var aSum = 0;  
    for(i = myLines.length - 1; i >=0; i--) {
       if(myLines[i].stroked) {
            aSum +=  myLines[i].strokeWidth;
        if(myLines[i] != refLine) myLines[i].remove();
    var newStroke = aSum / myLines.length;
    //create our new line in the same position as our reference line defined somewhere above
    var myLine = refLine.duplicate();
    myLine.strokeColor = refLine.strokeColor;
    myLine.strokeWidth = newStroke;
refLine.remove();
function duplicatePathPoints(shp1, shp2) {
    for(j = shp1.pathPoints.length-1; j>=0;j--) {
        var pt = shp2.pathPoints.add();
        pt.anchor = shp1.pathPoints[j].anchor;
        pt.leftDirection = shp1.pathPoints[j].leftDirection;
        pt.rightDirection = shp1.pathPoints[j].leftDirection;
        pt.pointType = shp1.pathPoints[j].pointType;    
function getConstructionPoints(path) {
        var pts = path.pathPoints;
        var ctspts = "";
        var x = 0;
        if(pts.length < 3) return [];
        for(i = pts.length - 1; i>=0;i--) {
            var pt1 = (i == pts.length - 1) ? pts[0] : pts[i + 1];
            var pt2 = (i == 0) ? pts[pts.length - 1] : pts[i - 1];
            var slope = (this.getSlope(pts[i], pt1)!=null) ? this.getSlope(pts[i], pt1).toFixed(2) : null;
            var slope2 = (this.getSlope(pts[i], pt2)!=null) ? this.getSlope(pts[i], pt2).toFixed(2) : null;
            if(slope != slope2) ctspts += "|" + i + "|";
        return ctspts;
function getSlope(pt1, pt2){
        var i1 = pt1.anchor[1] - pt2.anchor[1];
        var i2 = pt1.anchor[0] - pt2.anchor[0];
        var slope = (i2 == 0) ? null : i1/i2;
        return (slope == 0) ? 0 : slope;
