@SpiritedDreaming: It is also possible her Semblance is more powerful simply because of practice. I mean before going to Beacon, she mentions she was complete garbage until Qrow helped her be teaching her how to use a scythe, but Qrow doesn't have Super-Speed like Ruby so he can't teach that. Then she gets bumped up two years and once at Beacon, she is going to classes and occasionally takes part in combat class (the matches seem optional as Glynda mentions Blake hasn't taken part in it for awhile).

However after Beacon, she is now outside the kingdom with the entire landscape being closer to Mountain Glenn. She no longer can just go back to her dorm room at night, she instead is outside camping probably with nothing to protect her except her own teammates. We also know how dangerous the outside is based on Blake's words, meaning Ruby went from learning-to-fight to fighting-to-survive, possibly explaining the power boost in only 6-8 months.
