Bandit Camp Experience

Can anyone explain or point me to how experience is calculated after a bandit camp battle? According to castleempiresim.com the experience points per bandit is:

Guard Dog 2
Thug 2
Ranger 3
Roughneck 4
Metal Tooth: 160

Well I just sent my first wave into metal tooth's camp and I killed 5 rough neck and 149 rangers. I was expecting to get 467 xp but instead got 626. One possible explanation is that the rough necks are worth 6 points and the rangers are worth 4.

At any rate I would like to get an accurate listing. Anyone know of one?

I have also noticed I've been getting more experience than I should according to the numbers you will find here or on the battle sims. Maybe there is some bonuses that people have not been calculating in.

I dunno if castleempiresim has upgraded some exp or not. Recently, at the start of X mas event, they alter some of the exp we gain from bandits. Look at the patch note for details
