Ofcourse Dial Idol isn't accurate but it's the closest thing to the results than our guess. They are just basing it on busy signals. There's also the texting part of the voting which is not included in DI. This early in the show, DI is gonna have a lot of possible B3's. If you look at their predictions last week. They had a lot of them in yellow (not safe).

I've been following DI for several years now and they have been pretty good with the predictions. Just because somebody is in the last spot in their prediction, doesn't mean theyre the ones getting voted off. DI is pretty good with specifying the possible status of each contestants. Just pay attention to the margin of error and how close the percentages are with each contestant cause they could easy be switch.
I'm not saying DI is always right but I think it's the best prediction out there. The whole formula totally make sense to me. If only they could factor in the text votes, they'll probably be right all the time. But that would just be impossible.
Last thing... remember the week Chris Daughtry was voted off? DI got the whole night right. They predicted Elliott in the top2 while Katharine and Chris in the bottom. Considering Chris' popularity around that time, only a fool would've predicted it to be that way. But they were right. This is one of the several nights they got it totally right on the money.
