Dont know about the 4T for sure but her 3A looks pretty good she lands it multiple times in a row and with combo. I dont think its under rotated either. It looks light and totally unlabored. Plushenko is doing a good job and all that in off season and she wasnt even sure if she would compete. I think therefore its looking really good for her.
Sofia is very good at "concealing" under rotations and has been since for a while. I'm pretty sure I previously commented about how she (and some others, nationally and internationally) are dependent on the strictness of the technical panel, because their scores could end up varying significantly depending on tech calls. Obviously, she is not doing this consciously, it's just the result of her previous coaching.
A solid percentage of the videos I've seen have had missing rotation, though they definitely do look better (more effortless and more rotated) than they looked in 2022-23. Not necessarily due to technique, but due to strength - She looks so much stronger and more in shape now. Caveat - We have not really seen an equivalent of a competition situation, not even really a "normal" full training run-through with Ultra-Cs that are embedded in a full program. Essentially, it's one thing to jump things in isolation and another to jump them in programs, and then on top of that jump them in competition. Though Sofia is no Anna Shcherbakova with nerves of steel, she's also not like her dear friend Sasha Trusova who never ended up being able to land a 3A in competition (though that was partially a technique and a mental issue

), so we'll have to wait and see how she deals with the situation next season.
Obviously, as we also all know, tech panels are willing to overlook missing rotation (especially in Seniors, and that goes for domestic and international competitions

), so as long as she lands it and it isn't clearly a downgrade, she has more than enough chances to not get calls. (Might actually be a good idea after all to not do the JGP, because they've been more strict on the technical side in recent years, and once you have the reputation of UR your jumps, it can stick around like a curse.
