Find someone who has a schedule you like and go look at their reasons (composite) report, and see how they bid. The system is not all that hard to figure out and is fairly logical when you take a few minutes to learn it...you can easily figure it out on a few crappy overnights.
For some dumb reason the powers that be decided to remove all the PBS help videos from youtube. They did upload a few of them onto deltanet, but not the really good ones. Hopefully they'll come to their senses and put up the good videos.
