The method that you’re saying would be fair. But yesterday Aditya clearly said the bottom 5 according to judges votes are ———. Had he said the bottom 5 are ———— it would’ve been a different thing.
That's a small liberty I think. It may be that these are indeed the lowest rated by the judges, but the ratings are not the same for very one. AND the weight of the rating can make a higher voted contestant lose to a lower voted one. It is not a case of judges vote only - in Idol popular votes are the basic tool of decision making. Their importance keeps increasing as the show progresses till at the very end the judges have no say at all - it is all determined by the public. The judges are more powerful at the start of the show as it should be.
