Predictions Deadline
You must make your predictions by the time the results show begins, currently that time is : 12/16/2009 8:00:00 PM

Rank
DialIdol uses a weighted score to rank predictors rather than a busy percentage. The idea here is someone could get a 100% accurate prediction by predicting a range as wide as is possible (if there were six contestants then the predictor could predict all six would have a 1-6 range). To combat this DialIdol measures how much precision you specified in your predictions. If you predict that a contestant will finish in first place - your precision is 1, if you predict they will finish as high as first and as low as sixth (during a week with six contestants) then your precision would be 0.

How Precision Is Calculated
Precision is the weight applied to your accuracy percentage that determines your score. When you enter your predictions you predict a range where the contestant will rank. This range could span all the way from first place to last place and if you predicted in this manner it would result in 100% accurate predictions, 100% of the time. This is unfair to someone predicting a much narrower range who also was 100% accurate. Precision is calcualted as follows : 1 - ((High Range - Low Range) / (Total Contestants That Week - 1))

Everyone's Predictions
There is a special user called Everyone that represents the average of everyones predictions for each contestant. It might be interesting to see how well we all combine to predict versus DialIdol versus American Idol.
