Per the change after 2018 OWG to OWG qualification:
If the 2021 Worlds placements for the two U.S. ladies were to add up to no more than 13 (e.g., Bradie in fifth and Karen in eighth), then they would earn only *two* slots at 2022 OWG -- plus they also would earn the opportunity for a different U.S. lady (not Bradie or Karen) to compete at 2021 Nebelhorn in hopes of earning a third OWG slot there.
Where are you getting this information from? The governing document is the ISU's "Qualification Systems for the XXIV Olympic Winter Games 2022", available at their Olympics 2022 page https://www.isu.org/figure-skating/events/olympic-winter-games/fsk-beijing-2022 with the link to the file at https://www.isu.org/docman-document...tion-systems-3/22994-figure-skating-v1-0/file. That pdf makes it seem that 13 is indeed the magic number for 3 quota spots, with no need for the extra qualifying event. Was there another announcement that changed this?
