Hmmmm yes it is a bit odd! Almost like they don't want any of the others to go.
It's usually manipulated so there's at least 4.
So if the HM with the highest amount of noms gets 9, the second highest gets 7, the 3rd gets 4, and the 4th gets 3, and the rest get 1 each (for example!) the top 4 will be up! Even though the fourth one from top only got 3 noms.
This was verrrrry strange. Obviously desperate to get rid of Grant or James.
