I assume much of Rey's training will be mental. There could be reasonable explanation on her force power; I'll wait to see what it is before call it force-user power creep. I still think if Kylo is healthy, she gets her ass kicked in the forest.
Not only that - about him being healthy - but I think he just purposefully did not want to kill her for some reason.
He easily could have killed her earlier when he force restrianed her in position and defenseless and brought his saber near her throat. She didn't become so much more powerful just that quickly. He wanted info at that point so he did not kill her but easily could have.
He wanted to combat her one on one - testing her or something. There is no reason to believe he was not capable of force restraining her again at that point near the end and just killing her easily. He used the force to dispatch of Finn easily. Whatever physical distress he had would not likely have kept hm from being able to use the force in that way (some may argue it weakened him and therefore weakened his force as well, I don't buy that).
