Turn off Rain Sensing in the Settings menu. Set the longest delay on the wiper stalk and turn on intermittent wipers. If the delay between wipes is greater than 24 seconds, you fail. BTW, I sprayed water on the windshield during this test to prevent scratches.I did but it’s possible I missed it. I’ll check again.
