I enjoy watching this show. One suggestion is to eliminate the practice of voting off contestants when there are only 3 contestants left. Elimination at that point should be based on the number of contestants' correct answers.
I often see when 3 contestants are left, the 2 contestants (with the lowest number of correct answers) vote off the 1 contestant (with the most correct answers). This gives these weaker contestants a better chance of winning. So, you have a situation where the stronger links are eliminated by the weaker links. This seems contrary to the sprit of the game.
