I don't really know how the whole 'HP is TR' thing works. I mean, on the one hand no 11 year, however gifted, old works out a way to run hypercomputing algorithms on a closed timelike curve provided by time-turners. On the other, Harry presumably didn't start talking with an adult vocabulary when he was an infant, so... I dunno.

And sure, I can buy 11 or 12 year olds making observational discoveries. But for an actual, highly intellegent 11 year old who isn't sharing her mind with fragments of an adult's psyche, the correct tactic is to learn as much as possible, and start doing experiments when you're older, which was Hermione's plan.

Finally, this doesn't help because the concern is at a meta-level. Dumbledore, Harry, Voldemort, and Draco all got massive resource and power boosts. But not Hermione.

Certain of the female charicters did gain a power boost, while Baba Yaga is a new charicter and nicholas flamel is actually female.

Moreover, the way Dumbledore and Voldemort have changed is simply that they are acting like intelligent adults, rather than characters in a children's story. By comparison, Hermione is acting like a child rather than a child in a children's story, which... isn't that much of a change.
