I would rather it be 2 yes.
If i were a producer i would do the following - If more then 2 housemates are up for eviction, the nominated housemates will take place in a task. The last 2 who complete the task will then be up for nomination. Giving housemates a chance to save themselves.
or
If 3 housemates are up for eviction, the housemates not nominated will take place in a task to save. The housemate who completes the task first will then be able to save someone from eviction. Giving the nominated housemates a chance to be saved from eviction.
Either everyone is up or 2 housemates are up. Big Brother's word is final.
