Unfair !!

I am little shocked at the way Super Singer went on yesterday. I really dont know why there were 4 ppl who were eliminated earlier (3 long back) are again into this competitive round. Sadly 2 contestants are now eliminated. Is there any kind of recommendation happening here ??? I feel this is unfair. Agreed - that the RAC candidates were talented (only prasanna) but why did they had elimination ? I think there might some issues in the competition that made them to do this way.
