There’s also some statistic (I recall from last year or the year before) which shows that once they get past a certain number of total votes there’s almost always a 3 way tie at the end.
This means that it’s pretty much anyone’s guess who goes home. Check the Dail Idol numbers and it’s a virtual 3 way tie.
Yeah I remember that since with three phone lines, only so many calls can go in, in X amount of time. Also, keep in mind that stipulation that in the event of numbers too close to call, then AI reserves the right to say who stays and who leaves. So, they can pretty much pick whoever they want.
