Dial Idol's webmaster agrees that something is wonky with Lil's data from last night:

"Make no mistake about it - the predictions are simply too close to call this week. No one is predicted to be flat-out safe for the first time this season therefore DialIdol can't be wrong because it really isn't making any prediction.

I ran through a simulation of last nights vote - filtering out the dialers I had found last night who seemed to be getting a disproportionately high number of busy signals for Lil (even during the 9pm hour where filtering wasn't in place yet) and the resulting prediction still had Lil solidly in the second row on the chart though teetering on the brink of the third row where Danny was. Everything else was unchanged order wise. Also the predictions were still too close too call - much closer in fact. Here is what it looked like when I filtered these dialers out."

See link above for the chart and many iterations of data.

--And--

"It looks like there is some weird stuff going on with Lil Rounds prediction this week. I did some analysis during the first hour of voting and found three of 24 people dialing for her with busy percents way out of whack. Two of those three were calling from the same area code. I filtered those dialers out at about 10pm but the "damage" was done. In a way I believe this has more to do with a disproportionate number of callers for her compared to the rest of the contestants. She only got 40% of the calls that the next highest total. This makes her data very unreliable and probably over-inflated. If there are going to be any surprises they will probably come from her. I believe she is ranked higher on the chart than she the data suggests she should be."
