Sibling rivalry quest.

[Shairkon]

Hi.
I have a question about this quest... it's said that if you side with either of the sisters you get 5 exp points and if you can persuade them to coexist (need at least 4 in persuation) you get 6 exp points... Well, I tried siding with one then with the other, and got both times 1 and then 3 experience points... so 4. Howcome ?
