As we come to the end of the year Ana is broke in the top 10 and now she is #7 in the world, but that's not where she will stop. Till the end of the year she will most certainly be at least #5 even if she earn 0 points at Orange Bowl. It's because Bouchard will be erased from the list due to her age (1994), and Kontaveit will lose points from last year's Orange Bowl and Ana will surpass her.
But that's not all...Abanda is not playing Orange Bowl due to injury and she have only 22.5 points more than Ana so there are pretty good chances Ana can surpass her too with QF in singles and QF in doubles and become #4 in the world.
But even that is not all...Lottner, like Abanda, also don't play this year's Orange Bowl and she is only 48.75 points in front...with two semi-finals (in singles and doubles) Ana could become #3...Neither Abanda or Lottner are defending points till the end of the year, so it's all in Ana's hands but #5 is secured!!!
On the other hand, fewer than 100 points separate Ana from #16, and Orange Bowl is a GA, with lots of points up for grabs (250/180/120 for singles W/RU/SF, plus points from doubles).
That means that it Ana doesn't do well, there are many girls who could overtake her (Kulichkova, Bencic, Zhao, etc.). Ana herself needs to reach the QF in singles or doubles to gain any points.
