I think the 45-2x is perfect. It makes everything more exciting. otherwise it won't matter that much who the winner is. Like this someone who is 30 points behind can still climb up a lot by picking upsets and scoring a lot of points in comparision with others. If that wasn't the case risks won't be real risks any more. Like this every contest has stayed exciting till the end.

Just my view on this.
