They will be loosely based on previous point scoring.. if they're more likely to score high then their value will therefore be high. You can imagine Undertaker winning any matches he has, so he'd be a lot more expensive than, say, a midcarder who doesn't. I see what you mean, though, if someone like Tony Atlas continues to get lots of points like he has so far, his value would certainly go up from the small amount he's at now.
