I have a theory that the judges already have an idea of what score they will give before the dances are done.

I believe that Ali and Ricky could turn up and take a shit on the dance floor and still get 8.

In the same manner, Chris or Natalie could do a perfect dance and still get 7 or 8.

Ricky`s dance tonight is a case in point. Had it been marked on the dance then I cannot see how such a mistake filled performance could have achieved what was still a decent score.

Is it possible that during the rehearsal the Judges see the dance and have an idea of what to give it when it is done properly?
