I have done a little analysis of all the safe jodis marks and combined their result in percentage. These result are based on their marks from the last six episodes which they got from judges.
Yash & Gauri 155/180 = 86% (total marks for the last six episodes)
Shweta & Manav 147/180 = 81,6%
Shweta Raja 151/180 = 83%
Hiten Gauri 115/180 = 63,8%
Hussain Tina 160/180 = 88,8%
Tanaaz Bakhtiyar 177/180 = 98,3%
Just an analysis which showed if Shweta raja and Shweta manav will come in danger zone again than the chances of shweta raja is still high to remain in competiton.
