This year we were able to predict all the female finalists based on our model, but had some with the boys. This was largely due to data from Dial Idol; something strange was going on there with the guys.
Thanks to some internet spoilers, we know who will be in the Top 24 — but who will make it into the Top 12? We try to predict based on pre-exposure. Note that pre-exposure also has an impact on who will ultimately win, particularly in the last season.
