Yes, basically the producers know that the last act tends to get the most votes ... they are practically on screen as the phone lines open and their number was the last seen ... plus they are in the minds of the public ... so yes, they put the favourites last to ensure they get through ... so far no suprises .. Susan Boyle, Flawless and Stavros all last and all favourites ... the ones they don't want through will be hidden in the middle and instantly forgotten about!
