Looking at their AV's yesterday, if you consider total 95 days performance, I still feel Sai deserves to be more in top 3 than Smita. She fought hard with bullies for first 60 days with Megha and was sometime more forthright and frank in criticising them. It is only after that Astad nominating Astad incident around 75 days mark that she lost her focus.
But really don't know how voting pattern will go now. Everyone is going to be only voting for his/her favourite contestant. So, not many Megha supporters are going to be voting for Sharmishta. Smita will actually benefit from Resham not being there. More people from that group are supporting her ahead of Astad.
Between Pushkar and Sai, still feel Sai has some fan following. She twice got saved when she was in nominations after falling out from nominations. Pushkar was never in nominations since long.
So, if one can estimate the voting pattern, Astad-Pushkar would be the first ones to go out followed by either Sai or Sharmishta in 3-4 position. Then, Smita and Megha to be the winner.
Just a guess. No idea how it will go. I guess voting can be bought by money power too. In that case I won'e be surprised if Pushkar finished in top 2.
