Thinking things through here...
Route to the final
Competitors:
Alysa Liu: With a gold already in Lake Placid, any medal at Gdansk will put her in the final
Haein Lee: With a gold already in Riga, any medal at Zagreb will put her in the final
Russians:
Kamila Valieva: With a gold already in Courchevel, any medal in Chelyabinsk will put in the final
Daria Usacheva: With a silver already in Riga, a gold or silver medal in her second assignment (Egna?) will put her in the final
Ksenia Sinitsyna: Still to skate, but looks to be a favorite for silver in Chelyabinsk, so a second silver or a gold in her second assignment will put her in the final
Alyona Kanysheva: Still to skate, and status unknown, but earned two silvers last year. Repeating that performance would put her in the final.
Anastasia Tarakanova: With a bronze already in Lake Placid, a gold medal in Zagreb would put in the final
Viktoria Vasilieva/Anna Frolova: Still to skate, but likely to get anywhere from 2nd-5th place in their event. Earning a silver medal would get them a second assignment most likely, and another silver would put them in the final.
Maya Kromykh: appears to be out, with a bronze medal from Courchevel and a fourth place from Riga
