Warband Rating

I was unable to find in the rules how to calculate the experience of 1 group of henchmen. is it # of members X experience and that gets added to the total warband rating or is it the groups total experience added to the warband rating. So, i have a group of 6 novices which, as a group, has 5 experience do I add in 5 XP or 30 XP to the rating?
The sheets don't say Model # X XP so I wasnt sure how this works, also, it's not in the mordheim rulebook posted by GW. Any clarifications are appreciated.

Welcome to the forums!

Not sure of the exact location of the rule but the correct calculation would result in 30 XP (6 X 5). If you have multiple members of a henchman group you calculate the total experience of all the members of the group.

Cheers!
