To clarify, he wasn't sure if the difficulty for career mode was set based on the menu setting or not -- he just started it up and played and said that you can't change it during the mode. He did say that it was pretty tough fighting higher-ranked guys, but also that he powered through the low-level competition... my suspicion is that he was on Beginner/Experienced since that's likely the default level for the final game.
