I just thought that we should remind ourselves that when the contestants are called out each week - apart from the final two placings - we have been told that they are not in any voting order. So, for example: Rowetta (who was last to be put through last week) could infact have received most votes - and Casssie (who was called first) might have been third from the bottom. As for the final two acts, we only know that they gained the least votes, but don't know which contestants were in last place.
