If she's 5th in Grand Prix points this season how did she not make the Grand Prix final since there are six spots for the final?
She got 2nd and 5th at her events. The method of deter.ining who goes is points. Since she got 2nd (13) and 5th (7) points, she has only 20 points, unlike skaters who got only 1st, 2nd, 3rd (or a combination of the above). Skaters who got 2nd and 4th (Bradie Tennel for one), also have more points than here.
The next tie breaker is highest placing. While she would tie for the top 6 spots with this, she is already ranked at a highest of 10th overall, because she only has 20 points.
The 435 points refers to her combined scores at both of the grand prixs. This is used as the next tie breaker, but she is already ranked down at 10th, and therefore cannot be in the top 6, since points is the first thing to rank.
