So, I got out my abacus, and by my calculation, Sky Brown on 130,000 pts has now definitely qualified for Paris. She currently sits an effective 9th when the 3 per nation rule is applied, so to lose out altogether she would need to drop 12 (effective) places minimum in Budapest. However, given the scoring system, it is not mathematically possible for 12 athletes currently below her right now all to get enough points to catch her - obviously, and one athlete can by winning in budapest to get 210,000 pts, but 11th only gets about 45,000 - I don't think there's any mathematical way that 12 athletes (not including 3perNOC duplicates_ can ALL get past her.
