What happened in today's challenge could happen in any such challenge. The shorter challenges and the rules to drop girls off were implemented to keep the ladder short.
As for 10 and 15 votes I agree, but that is no longer allowed by the moderators.
@MelisaFanAnita2: I'm sorry you feel that way. The ladder represents the tastes of the people that usually vote, obviously by that standard Jana would not be top 10. In my personal ratings she is number 199 at the moment.. I've missed out on some challenges that saw girls drop off that are high in my rankings, but that's all in the game.
