Right.....I see what you mean Bran. Having 3 in the semis is a sticky situation as even if there was NOT a tie for top place tonight then the two situations would be either:
Judges vote 1 + Public vote 3 = 4
Judges vote 2 + Public vote 1 = 3
Judges vote 3 + Public vote 2 = 5
so the bottom person definitely in the dance off regardless getting the highest amount of point from the public
OR
Judges vote 1 + Public vote 3 = 4
Judges vote 2 + Public vote 2 = 4
Judges vote 3 + Public vote 1 = 4
The only way Tom would have been saved tonight (this is of course assuming the top two were NOT tied as they were) is if the second scenario happened and then he would have been the only one NOT in the dance off as the public would override everything.
You would think that there would be someone at the BBC doing all these calculations as it is already slightly dodgy having 3 in the semi finals. You would also think they would have worked through the "what if there is a tie for 1st and 2nd place" scenarios already. They should have already worked out that if that happened then there would be no point voting for whoever was in 3rd place as they would definitely be in the dance off. They should therefore have had this up their sleeves and should have said at the end of the first show - right, clearly Tom is in the dance off so therefore vote tonight for either Lisa or Rachel to join him in the dance off. That would have saved all this nonsense.
It just feels as if the BBC didn't think the maths through enough on this in advance and were caught on the hoof....
