I'm not so sure taking the last cycle plus two pandemic years as a baseline is necessarily indicative of the coming cycle. After a two-year-disruption, it's been a weak cycle, Gilles had cancer when G/P looked most competitive, and the system is now rigged for choreographic elements rather than skating. I think the teams behind them 5th and down overall are stronger than the teams that were in the last couple of cycles. I can't imagine that since they've, or at least he's, said that the goal is to win everything next year, he hasn't looked at the field and said, "Hold my beer," whereas he might not have had the competition been stronger.
I don't think age is to their advantage, but experience certainly is. (Papadakis/Cizeron were young, but by 2018 they had as much experience at the top as any of the teams competing now, and they had the continuity of having Haguenauer in their court.) They don't have to move, they don't have to get used to IAM, they know each other well, [Edited to remove: and their funding from Quebec is probably settled since they're skating for FRA, doh). They have to keep healthy, adjust to each other, and respond when assumptions they made prove to be false, forcing them to work through them.
I'm not so sure if they do reasonably well this year and decide to go to 2030 they'll find the skaters coming up now such a pushover, although because the French Fed is comprised of idiots, Lopareva/Brissaud are likely going to get rolled over.
