A simple rope hanging under the force of gravity will have strain > 1.
What you probably want is to compare the strain to a threshold (eg 1.1, 1.2, etc). If the strain is over this threshold, then you consider the rope as "stretched".
I have found out that due to the rotation of the rope the strain was calculated for the oposite site.
Indeed , the threshold has to be around 1.03-1.05 for stretched parts.
I want to thank you for the great support that you have provided in every single post !
