Facebook messenger favourites

How does messenger select these top 15 contacts? I have seldom f ever communicated with a couple of them. Yet others who I have messaged are not on it. Just wondering what's going on??

Re: Facebook messenger favourites

Well I'm no expert on the matter, but I'm guessing that some of those "favorites" are just people that happen to be online.. But is it really that big of a deal???
