why were 5 up for eviction when jim/liz had 5 votes each

seems harsh on Evander only having received 2

because Big Brother said so.

Jim hasn't got pissed yet and had a massive argument with the Nolan woman.

So that the public had some say in who went, rather than lee and Casey just picking from Liz and Jim

Because for the twist to work they needed more than two so the bolt hole could choose, as the rest got two votes each.

Last year they had 3+ up;

a) it stops the one v one negative voting. and

b) more phone calls, more money.

It seems to be that since mid BB14 they changed it to any housemate with 2 or more nominations face eviction. They never confirmed it as far as I'm aware, but that's what it seems to be like.

There is an upside to this: the HMs can't know so easily who voted for whom. It's always been a potential game breaker that they could work it out, and then it's a straight split into two teams.

I think that in order to avoid the 1 vs 1 situation they made a decision to have a minimum of 3 housemates up for eviction each time.

If it had just been two for tonight then it would have been Jim vs Liz. By going for a minimum of three they had to include the next highest nominated which was 3 people all with 2 noms each. Presumably if one other housemate had received 3 noms then it would have just been them.

As another poster has said, this has some positives to it but the down side is that you get situations where one or two housemates have loads of noms and therefore other housemates with very few noms find themselves up as well.
The biggest positive for me is that dull housemates who had previously sailed through entire series because they only got a couple of noms each week now are more likely to face eviction sooner - as happened tonight.

Of course the reality is that the producers change the rules regarding noms so many times to suit themselves that its tricky to keep track of what the criteria is.

But Luisa had 3 noms, and Evander and Jasmine had 2 noms.
