I'm sorry, but that isn't the same logic. I am unsure how V can tell that shi is the same level as Z, but shi did say as much. Is there a similar sentence from either Elan or Nale? Because I disagree with the statement that the are "rivals" (which I take to mean the kind of relationship that ties Haley and her sworn enemy). They are opponents, certainly, and they dislike each other, but that cannot be enough to tie levels gains. That would require an extensive background, not just being enemies since Nale run Elan through.
