let me see if I can simplify this
when the power harness stretches it will cause your draw length to become shorter and you will loose poundage and will not get full cam rotation
if your string stretches it will up the poundage and lengthen your draw and will give you more cam rotation.
either way will cause the bow toshoot off because the nocking point and peep will be in a different location.

sure you could move the peep and nocking point and have it tuned with a stretched string or harness but either way it has in effect changed your draw length and changed the rotation of your cam to some degree
which in turn has an effect on the bows preformance.
the best thing to do in such situation is to twist which ever needs to be shortened due to it stretching
this will bring every thing back to its original position

Is any of this making any sence?
I hope so because I dont know how to explain it any better[8D]
