Story Mode Gachi Battle guide?

Is there a Gachi Battle guide somewhere online? I'm at 98% with Olivia because I don't know what to do against Cedric. I know Gamefaqs has info on how to access everyone's alternate path, but it has nothing on the Gachi Battles that take place afterward. I just experimented with a bunch of stuff in her GB with Odille and that worked but it's not working against Cedric.

EDIT: I found a makeshift guide here. As you can see he's quite unsure about a lot of it since he translated it from a Japanese Wiki entry. I plan on testing things out and eventually writing a guide. The fact that the game gives you no hints for Gachi Battles is it's biggest flaw if you ask me.

You know I would love to see a tutorial mode in other games like BF ans SFIV thats like VF4's tutorial mode. I just think it would help starting players.
Of course I think I would be sweet if SFIV and BF had "World Tour Mode" like SFZ3 did. That was fun.
