Weekly contest doesn't add up

Anyone experience this or have feedback? I've won the weekly contest/challenge the last 2 weeks but this week someone I'm competing with that I don't know has already passed way over 200 more levels for this week's competition... That's way over what I've passed each week I've won.... No way I can compete with that if she keeps up at this rate... No point in even trying... Strange that just a few minutes after the competition started she had passed 24 levels already ... How is this possible?I kinda feel cheated.
