augieboo: I don't think my system would work if many of the components did not work far more often than not. The point I keep trying to make, is do not get hung up on one or two signals you think can not fail. They all fail.
The secret is to find and use a combination of components in your strategy, method, system or what ever you want to call it, so that more often that not the components will clue you as to when your method may be failing. If you can achieve this, it will greatly improve your overall performance.
