Now we know?
I have been using this "method" for a quite a while now.
I think one of the problems for you newbies is you dont understand the central issue. We have been in a consolidating market for almost 2 years. So this "method" has worked quite well, even though there have been period of weeks when there was no signal. Its the same with every system. In order to make it work, you have to have the discipline to wait for your signal.
Welcome to the party, and by the way, would you shut the door and turn the lights out when you leave?
bye
