Is this really a deep knowledge of how something works or is it because of trial and error you found the best way. It could be good old common sense at work here. By the way, I know exactly how our dishwasher works. I am slow but steady and work for free:-)

Mike how do we know that the engineer applied an algorithm here. Maybe she just got lucky and did the right thing. Maybe it was just good old common sense. I do agree that an algorithm w/o understanding can be applied incorrectly.
