Wouldn't call that dancing, more like stomping teh rug.
You are quite skillful. I've tried that once and it didn't go too well.
My friend is way good at those dance games. We were at arcade once and he danced on a machine. In 5 minutes he had a crowd of 10+ people watching and he just went on and on dancing. He never lost, just got new credits over again. T'was cool.
