I think there is a tendency for some folks to over complicate things and no doubt there are those that get satisfaction from their tinkering with things. Having sold and installed filtration equipment for over 30 years now I have to say that the vast majority of my customers are happy just having the darn thing in the basement doing it's job with as little input from them as possible. Most folks just want the equipment to work. They don't get all involved in the minutia of programming and trying to save a half teaspoon of salt or a gallon of water either. I program for the "least amount of phone calls" most of the time.
