Oh, absolutely. Well, short of the way that Labour elect their leadership, which nobody appears to understand.

But in some ways it seems simple:
Judges vote, points allocated in order of score.
Public votes, points allocated in order of score.
Score of contestant = Judge Points + Public Points.

I think that giving the tie-break to the public gives people more of an incentive to vote - and that handing the tie-break to the score given by the elitist ruling classes is a disincentive to direct democracy :->
