Well, that's not really accurate.
GilPoir have lost to FearGib twice now - last year's GPF where they had a major error in the RD that left them too far back to make up the ground with FearGib, though they did beat them in the FD; and now this past weekend. They've beat ChoBat 3 times during the last 5 seasons, going back to 2021 Worlds, while ChoBat have beat them 8 times. And prior to 2021 Worlds, I'm not sure they ever beat ChoBat at a major competition (Worlds, 4CCs, GPF, Olympics). I'm hard-pressed to see how GilPoir have been dropping this entire quad (especially seeing as they moved ahead of GuigFab in 2023-24 and have remained ahead of them since), and certainly not to "less skilled IAM teams".
GuigFab have, indeed, lost ground, but they very much did that to themselves and they did it last season when they came out with two anemic programs and it finally caught up with them at Worlds. They still beat FearGib (in both phases of competition) at the GPF and Euros last season. Then they showed up at GPdF this year with another set of anemic programs. Sure enough, the judges walked through the door they gave them, especially since FearGib do have better programs & Marco's skating skills are now painfully, obviously deteriorated compared to where they were at the start of this Olympic cycle. And have GuigFab ever beat ChoBat at a major competition?
There's an awful lot of entitlement, I think, on the part of both GilPoir and GuigFab, in believing they were going to stay at the top of the ice dance hierarchy through this entire Olympic cycle without putting in the work to produce good programs consistently or to take the feedback the judges are giving them with the GOEs and PCS marks to improve the programs they do have as the season progresses. And that particular Achilles heel has proven to be their downfall against some teams who DO put the work in to continuously improve their programs over the course of the season. FearGib came into this season with a really great concept for their FD and a decent RD (as decent as one can expect with this horrible 120bpm requirement). But they also have been absolute workhorses in the off-season and they've gotten out early in front of the judges each season & taken the feedback from Bolero Cup & Nebelhorn, etc, and made the necessary changes to keep improving their scores, and they're also not making major mistakes in their programs for the most part, which has put them in the position to capitalize when their opponents show up with subpar programs & make mistakes.
