Why was Tracey allowed to win this week when it was obvious that her game plan was to give low marks to the others and to complain about everything. Her food, comprising mainly cupcakes, was rubbish and giving scores of 2, 4, 4 and 5 ensured she would win. The producers need to stop this type of game plan as it spoils the show.
It's interesting that you say that hc4361 because I live in France and they have their version here called "A Dinner Almost Perfect" and the contestants are all normal but tend to be good cooks.
They mark out of ten for the food, table decoration and for entertainment, so a maximum of 30 marks/person. It's a very popular show here and very watchable and it certainly goes to show that you don't have to have unbalanced people or those with super egos to make a good show.
