I like your enthusiasm.

But actually the USFSA never gives byes for Nationals (except in the case of injury), for the reason that this would undermine the interest in and importance of their own event, which they would like to promote as vigorously as possible. Buy a ticket! Come see Amber Glenn, Ilia Malinin, Chock and Bates, fresh off their Grand Prix triumphs!
In the olden days, placement at Nationals was essentially the
only factor for being making the world team. Even under the current rules, placement at nationals is the highest-weighted of the several facrtors that the Selection Committee takes into account. But the Grand Prix Final is #2.
They also take into account, to some extent, the previous years' experience, especially placement at 2023 Worlds. However, "trending" results are given more weight than yeah-but-:what-have-you-done-for-us-lately ones.
Anyway, without getting too far ahead of ourselves, Amber will be a shoo-in for Worlds if she finishes first or second at Nationals, and will probably be selected if she finishes third or even fourth. Isabeau has fallen off the pace this season, but she did get fourth at last year's Worlds, so she, too, will go if she finishes first or second at Nationals. But there will be lots of competition -- Alysa Liu and a bevy of newer aspoirants. I can't wait!
