JS CS3 flag duplicate images with scale and rotation differnce

I've been trying to cut down on the number of images a script I have would produce.  The old script would look for links that are being used multiple times and then just version the link which is fine.  What I am finding this that although a document may have one image linked 9 time 6 times out of the nine the image is scaled and rotated the same amount and the other 3 times the rotation and scaling also match. In this example the image only needs 2 versions the first as the original and the second with the scale and rotation of the image used 3 time let say.

So to the code:

The following code will work through the doc and create an array of the links as duplicates:

function LinkUsage(myLink) {
    var myLinkCounter = 0;
        for (var myCounter =  0; myCounter < myDoc.links.length; myCounter++) {
        if (myLink.filePath == myDoc.links[myCounter].filePath) {
            myLinkCounter++;
        }
    }
    return myLinkCounter
}

var myDoc = app.activeDocument;
var myNumLinks = [];
        
for ( var t = myDoc.links.length-1; t >= 0; t-- ){ 
    if(LinkUsage(myDoc.links)>1){
            myNumLinks.push(myDoc.links.id);
        }
    }

Is there a way to loop through the array and only flag the differnent scale and roatations.  What I should get is that out of the multiple link uasage the image is only changed twice out of the 9 times used.

I was trying to loop through the array and then loop through it within the loop to compare the link but this does not work for obvious reasons.

for (var i=0  ; i <myNumLinks.length; i++){
    
    var valLink = myDoc.links.itemByID( myNumLinks);
        if(valLink.parent.constructor.name == "Image"){
        
            for (var j=0  ; j<myNumLinks.length; j++){
                if(myDoc.links.itemByID( myNumLinks).parent.constructor.name == "Image"){
                    if(valLink.parent.parent.images[0].rotationAngle != myDoc.links.itemByID( myNumLinks).parent.parent.images[0].rotationAngle){
                        $.write(myNumLinks+"\n");
                        }
                    }
            }
        }
    
}

Is what I am trying to do possible and if so any suggestions would be appreciated.

Cheers, John.
