2 double eviction week

So this week will end on 8th - if 2 contestants gets evicted , we will still be left with 8 contestants.

Next week will end on 15th - if only 1 contestant gets evicted , we will be left with 7 contestants

Coming week and the final week for eviction will end on 22nd - if only 1 contestant gets evicted then we would be left with 6 contestants.

So will we have 2 or 3 double eviction week or has BB decided to carry forward 6 contestants in the finale week instead of 4
