We need someone with a maths brain to work out all the various permutations Kiwi and two couples tied at the top and two at the bottom didn't they which skews everything.
Did it go 6-6-5-4-3-3? If so, and you went in reverse with the public vote you could end up with one couple with 9 points, four couples with 8 points and 1 couple with 7 points, with 1 bottom couple receiving 9 points and one top couple receiving 7!
I think Gemma, Mollie and Davood are the ones in danger of being in the dance off.
