1. A baler implement comprising:
a baling system having a baling chamber configured to form crop material into a bale having a cylindrical shape;
a wrap system configured to feed a wrap material into the baling chamber to wrap a circumference of the bale with a number of wrap layers of the wrap material during a wrap cycle;
a wrap sensor configured to detect data related to an unstretched length of the wrap material dispensed by the wrap system during the wrap cycle;
a bale size sensor configured to detect data related to a diameter of the bale within the baling chamber;
a baler controller including a processor and a memory having a wrap stretch algorithm stored thereon, wherein the processor is operable to execute the wrap stretch algorithm to:
determine the unstretched length of the wrap material dispensed by the wrap system during the wrap cycle from the data sensed by the wrap sensor related to the unstretched length of the wrap material;
determine a circumference of the bale in the baling chamber from the data sensed by the bale size sensor related to the diameter of the bale;
determine a stretched length of the wrap material as applied onto the bale during the wrap cycle from the circumference of the bale in the baling chamber and the number of wrap layers of the wrap material; and
compare the stretched length of the wrap material as applied onto the bale to the unstretched length of the wrap material dispensed by the wrap system during the wrap cycle to determine an applied wrap stretch factor.
