I only have 2.87% luck so I guess that doesn't affect the drop rate. I do change my alpha to match the judge if that helps ( I noticed that the cash amount and item drops gets higher when the alpha and judge has the same attribute or is it just me.)

Actually from what I can tell aside from Luck (ie. crit chance), Hardcore (ie. dmg modifier) and Ego (ie. HP) the other stats seem to have minimal to diddly squat effects even with the judge attribute bonus. I swapped out Bunny for Juliette when the Charm judge was on and didn't notice any difference in the battle. The only part that really matter is if the judge picks the same Sex Position the Alpha likes as it increases the ego dmg to your opponent. Even then a well geared person with higher Ego or higher Hardcore to outdamage the buff can mitigate these bonuses anyway!
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.
