Some have asked why not just set each computer to use default 3:00 AM automatic update settings. The answer? Because AU doesn't support optional updates which are often "vital" in my opinion. Things like certain application updates and root certificates updates to name a few. AU doesn't do that sort of stuff. Kind of like comparing a microwave oven to a "real" oven. Sometimes the bigger stuff needs a bigger oven. In my case, three were 100 percent. One was 98 percent, so I call that 99 since I use Enron math.
