armor king and money in tekken 5

Last night I was playing Armor King in Ghost Battle and for some reason, I was getting RIDICULOUS amounts of money with him. I'm talking about over 10,000 for almost each match, and each match had a bonus too. I was just wondering why that happened. Is it just a glitch, a special thing with Armor King or was I just doing well or something?

in ps3 verson?

Ive noticed that most of A.King's moves have a decent amount of wind-up, so keeping mid distance puts him at a disadvantage. I also think its hilarious with how the A.I. spams the same moves repeatedly, let alone an actual player.
