90% of the time she curbstomped EVERYONE until she meets someone that actually gives her a challenge, remember, she has beaten the ENTIRE school
It's not a curbstomp if it involved her getting beat up for 2/3 of a fight.
The point isn't that she's won most of her fights, but that a lot of the time she either just barely wins (see the Elite 4), or she has to go through a thorogh beating before she does.
Seriously, the only fight I remember her winning without any problems whatsoever was the Biology Club.
