I think you're right about subtracting points, but I have a feeling that the workers making eachother look bad could come off poorly on TV and expose the business.
Plus, I think the booking team would be too tempted to make it gimmicky and lose the shoot feel with heel and face judges, judges purposely not callingit down the middle.
Sounds like a comedy act to me are they going to bring in a british judge who will be rude to everybody, a model that loves everybody, a neutral judge that talks only in slang, and Abismal Negro who will give everybody a negative score?
If only William Regal were available...
