You're the one who claims paranoia. I've done "tracking". For the most part, beyond a very narrow use, it's worthless. It also takes up a lot of human time to evaluate what you have. Just because you've got a digital signal doesn't mean anyone can write up programs to accurately analyze it ~ look at the Global Warming Models for example. The AGW people really screwed up. They wrote programs to accept only the data that would support the results they wanted. Now they're discredited ~
Think of the billions of dollars they wasted on that nonsense. Do you really think "the government" is going to spend that kind of money finding out what driftdiver does?
