But under 6.0, would there be even the slightest chance that Laura Lepisto would (deservedly) be in the lead right now?
I think there's not the slightest chance she'd be in first under 6.0. One of the good things about COP is that it does force the judges to recognize unknown names who have a great skate. There's still room for manipulation, of course, but if someone lands the only 3-3 in the competition, they're going to be rewarded.
