Half the problem lies within the fact that by default, two of the judges can't make a decision because their acts are in the bottom two (apart from weeks where a judge has two acts in the bottom two); so it puts the decision down to the two other judges. ONE judge will give a genuine vote for who they think should go; and the other one will chicken out of being the bad guy and take it to deadlock.

The judges should not be getting a say in this; they are redundant.
