I might sound unpleasant and stupid but here are my views on this entire show:
(a.) First and foremost this is a show to generate revenue for Zee TV, for they are in serious business.
(b.) Therefore, they will go by what people want to see in the show. If they want to see Rajeev becoming the winner, they can do that as well. How do you know that the elimination based on the SMS is authentic? They might make up the numbers and we have no way to come to know about that.
(c.) It is "their" show and thank God that so far they were maintaining some purity. But even before c2005, in some of the earlier rounds, I felt that the results were not truly reflecting that day's performance. After all they must be paying something to the contestants or based on their availability for the next recording, the results must have been influenced/altered. We all know that what we get to see is not the "whole" show but edited and abridged version. So it is all in the hands of editors to highlight the good or bad or OK performance to "justify" their decision. I have heard this kind of allegation by many film stars who have alleged some directors to have "cut their scenes" or "truncate their roles" in the movie after the shooting is completed. So it could be very much possible here too.
(d.) Many times I have felt that couple of rounds were recorded in space of 1-2 days only. For example all the episodes with Shiv Hari appeared to have been recorded in space of 2-3 days. Definitely it was not week by week basis. Think of it anyway, to get all the four mentors/judges/guests on same day and same time at same place is anyway difficult.
I can go on but suffice to say that all these shows are not "real competition" and one should not get too involved. Enjoy the show on its merit only and do not read too much into that.
Have fun. 😊 😊
