Illustrator Scripting :: Copy / Move And Paste Into Different Layer

I have a script that measures the repeat interval and gap between print impressions printed using a print cylinder (for the production team to know which print cylinders to use, and what to expect once it prints, when looking at the proof sheet). Basically it just measures the distance from the beginning of one print impression to the beginning of the next (these are printed with a cylinder, so every time the cylinder rotates a new print impression happens) as well as the distance in between prints. That part works great.
 
In order to get these meaurements, Illustrator is measuring the distance from a zero point on the artboard to the left side of a marker I made called "repeat", and it is assigned a variable called rawRepeat. What I'd like to do is have the script take that rawRepeat value and use it to move a copy of the print impression to the right by exactly that variable amount and paste it beneath the marker called "repeat". I have been doing this part manually, but haven't been able to figure out how to get illustrator to do this for me.
 
Here's the script I am using:
 
var myDocument = app.activeDocument;
var selectedObject = myDocument.selection;
var activeLayer = app.activeDocument.activeLayer;
var layerName = activeLayer.name;
activeLayer.name = "plate";
