@Cherry2000: suggestions are always welcome, no worries ;-)
Actually the last suggestion someone made caused the rules to change a bit, now if a girl gets no votes in a challenge, she falls off the ladder. This happened to Jennifer Galbina. I think it's an excellent rule, and if a challenger ever gets as high as Silver, it might happen to Silver too.
As for using the card ratings, well, they in themselves are a bit flawed, just check out the many threads about them. Girls either get a 0 or a 10 most of the times. But again, thanks for thinking along!
