As I understand it, the judge "attributes" have actually nothing to do with attributes. Each girl has a main stat (hardcore, know how, charm) and a favorite position depending of the main stat, and then, the judge will choose a position between each main stat according to the pourcentage. For instance, Love tseu will have 70% chance to choose a know how position, 25% a charm position and 5% a hatdcore position. It means if you have an alpha girl with charm, her favorite position has much more chance to be chosen than if you have a hardcore girl. You deal more damage (20-30%?) during the favorite position

This give a slight edge in fight, but it doesnt affect stats.
