Facebook - 9 Friends Box and Friendslist on Timeline.?

[Mia]

Hey you guys!

I just started to think about the arrangement of the 9 friends and also the friends list on timeline. But not on my own but on a friends timeline. I just have one mutual friend with this person. In the Box of 9 are people i know she's interacting public quite some time, the roommate and some she's interacting publicly sometimes but not very often. But also there's a girl who doesn't like anything of him and she just liked two pictures of her. Don't know about private messages or comments on Status.

When i look at her profile the friends of the box are all in the Top 20 of her Friendlist. Also there are two girls whose profile i viewed very often, but we did not interact at all and we aren't friends. In the Top 20 of the Friendslist of my friend, are always the same people, maybe 2-3 change from time to time. I did a second test with those two girls profile i viewed a lot. For the last month i did not even once click at there profile or pictures. I found two new people whose profile i viewed often. But the two girls are still in the Top 20 and the two new aren't...

So how does Facebook decide which friends to show first?

Thanks for answers.
