They said "plus an exclusive performance" and everyone knows the guest performs in the results show, and Dermot kept saying it too so if someone tuned in just to see Britney during the first show surely they would have figured it was in the second show and turned off?

How do you know they all know that? The results show are always the least rated on the night. Britney was advertised all week on be on The X Factor, not on the results. It says the peak was 12 Million, so people could have tuned in at any given point to see what's happening with it.

I'm not making excuses for it to be Britney's appearance, but it's quite obvious the ratings increase was because Britney was advertised to be on the show.
