I have no clue what happened with the "wrong numbers" vote.
Honestly, I can't see that most people would make that mistake. The top numbers were correct and the bottoms, which are smaller, were off. But I think most people who vote know what numbers to push.
I actually thought it was a scam to get an extra night and more "ratings" from the show. Follow the money...
I do agree with you that most people know the number of the person they are going to vote for. Just seemed odd that only 3 of the numbers were wrong. Not all of them.
