I think actually the strength is that the audience can
disagree. Yes, when the numbers are small, they can reverse the leaderboard, but we're talking about three couples, four at the outside. I can't think of a single example when the top couple of five or more has been eliminated- and very rarely would the top couple even be in the bottom two. The chances of it happening are pretty low, because it depends on the exact voting order.
eg. Series four quarter final
Judges ranked the couples (IIRC)
Emma 5
Louisa 4
Carol 3
Mark 2
Matt 1
The public then voted
Matt 5
Mark 4
Louisa 3
Carol 2
Emma 1
Leaving overall
Louisa 7
Matt 6
Mark 6
Emma 6
Carol 5
If you assume this was to win rather than to stay in the competition, Matt won the public vote and the outcome was noticeably odd, but it still wasn't enough for him to win overall. I don't think any outcome has come close to that either.
So the public can
make a difference, but they can't
reverse the leaderboard. All that happened last night was that the theoretical possibility of the bottom couple winning in spite of being the worst was removed... but the chances of it happening with six couples were pretty low to begin with because of the maths required.
If the public can totally reverse the leaderboard, it makes a nonsense of having judges. The idea is that the public voting on likeability and entertainment, combined with the judges voting on dance merit, produce a winner that compromises these two factors. Ie for the quarter final scenario- the judges can't force an Emma win because she is unpopular, and the public can't force a Matt win because he isn't a good enough dancer. But we can compromise on Louisa, who was second with the judges and third with the public.
