Rey doesn't go through any of these progressions. She goes from 0-100 in everything.
She was pretty damn good at staff (melee) combat before even seeing a lightsaber. She clowned several fools, and her proficiency with her staff was well established well before any force stuff came up. So that's like going from awesome at a car racing to pretty damn good at truck racing. 90-100. And then racing someone is a truck with damage (injury).
As for force stuff, there's plenty to suggest that some are just good right away. Anakin's pod racing as a pre-pubescent boy when they established that literally no other human could do it because they lacked the reflexes. Qui-Gon pretty much said, "yup, he's pretty good at pod racing because the force. In which he has no training. At all." He was established as the chosen one? So you want someone to hold your hand and spell it out? Show, don't tell. Hint - Rey is going to be an important and powerful player in the Star Wars: Force is Forcing series.
And you ignore the fantasy aspect of this all, which is absurd. The force is the deus ex machina for
everything in this series. Everything. If Rey's powerful, it's because the force, not her ******. Maybe we should bring back midochlorians and we can chart everyone and whoever is called the chosen one (which puts its own limits on storytelling) can do whatever but others with less midochlorians can only do what has clearly been established in a training montage (complete with 80s music).
My point re: VaginaWildcat85 was not to be mean but to point out that your polar opposite, who sees everything as male oppression, would see almost
every other movie in a similar but opposite way. In other words, you see the movie through
your lens. Your lens is just high on perceiving slights that aren't there re women. Your problem is with the pacing of the hero's powers, which is a legit criticism that others have. But the fact that she is a woman does not make that a PC overreach issue. She's a woman, and her character has a plot development issue that is unrelated to her womanhood.
And everyone is missing the elephant in the room. JJ Abrahams, and everyone working on Star Wars ever, is human. Humans are always the most powerful (good and evil) in this galaxy filled with an absurd amount of sentient species. Even Yoda failed and had to get humans to clean up his mess. The agenda is transparent.
