If they really want to be fair they should average the scores from last week + this week to arrive at the elimination next week. Isn't that what they did some weeks earlier when there was no elimination? There is just no consistency and fairness in their decisions!
This is extremely unfair to contestants who performed well last week and got less scores this week and gives an unfair advantage to contestants who did not get very good scores last week.
Why don't they just hand over this trophy to their wonder kid? The judges are being obviously biased and partial.
