We've talked a bit about placement for the top three ladies, and also the Russian issue re: the unseeded Medvedeva. The latter also interacts with the politics of the second bracket, the fourth through sixth seeds.
There's some uncertainty here since Kostner is the fourth seed, but she may or may not be retiring. If she retires, then Alina is fourth seed, Bradie the fifth, and Gabby the sixth. Bradie would pre-emptively get Skate America, and Gabby Skate Canada (if there's any good news for her out of how Worlds went, it's that she and Kaetlyn aren't in the same seed bracket anymore and so can both do Skate Canada).
Alina then gets to pick first, and here's where Russia's decisions regarding how to handle her and Evgenia will really come into play. If they're absolutely set on Evgenia and Alina doing different events, then at first glance Alina should pick something other than CoR, because that means Russia can give Evgenia an invite there and only has to arrange an invitation for her to one other event. But on closer inspection that's also kind of unforgiving, schedule-wise:
Oct 19 - Oct 21, 2018 Skate America
Oct 26 - Oct 28, 2018 Skate Canada
Nov 02 - Nov 04, 2018 Cup of China
Nov 09 - Nov 11, 2018 NHK
Nov 16 - Nov 18, 2018 Rostelecom Cup
Nov 23 - Nov 25, 2018 Internationaux de France
Assuming they want to give Alina and Evgenia both some breathing space, then the most logical pairings are CoC+CoR and NHK+France. Getting Evgenia and invitation to France should be easy enough, but it will depend on whether (as we discussed above) the Japanese are such good sports as to give her an NHK invite.
Although Alina is seeded and garaunteed two spots, she won’t choose her assignments, she will be at the mercy of which Fed gets to make their choices first.
