Mike the wider of a fan spray pointed directly at the clothes the more effective it is. When I check the "Extra Softening Rinse" box on the computer interface for the Super-Unimatic, instead of a 2 minute overflow rinse the computer gives a 2 minute spray rinse and no overflow, this allows the fabric softener not to be diluted by the overflow rinse. When the spray rinse first starts you can really see the sudsy/cloudy water coming out of the clothes, but by the end of the two minutes the water that is hitting the glass on the side of the cabinet is usually nearly clear. Two minutes is more than enough or about five gallons.
