Six Flags Over Georgia Flash Pass?

We're planning a trip to Six Flags Over Georgia in about 3 weeks. I've read the site about the flash passes and the 3 levels and their prices. I'm wondering if someone can explain to me in a little more detail about how each one works... more detail that the site provides. From what I understood so far is the basic one allows you to check in and then go do something else during the wait time rather than standing in line (thus stand in line for another ride and then go back to the first one). Which to me, means you basically wait in line for one and ride 2 and then so on. For the next option it just says less wait time and the platinum option it says the least wait time and you can ride each one twice in a row. But, I'd like a little more detail mostly about how the second and third option work?? There's really a big price difference. Can you just run through the park in the beginning and flash everything you want to ride and then go back and ride them? Or do you just go up and show your pass and ride whatever you want whenever??? Please explain. Thanks so much.
