Yes.
ThereS no criteria, and no ability to mark to that criteria accurately - or watching 6 people at once , with 4 markers who spend most of their time playing around with an order sheet and not watching. What they see is random, how they mark it is random.
And its impossible for the audience - as they can't see what any judge who may, or may not be watching at all. sees, or claims about seeing. We can't see more than one or two people at once, anymore than one judge not looking at the table can see 6.
It serves only one purpose - to allow the judges to reshape the leaderboard for the producer's, or their own ends.
And that can only have one result - - their scoring can't often be defended from whats seen , or obvious , so it suggest that there's something else going on.
