I've been playing with this format in BB, but I'm realizing that it works much better for ranking The Challenge games. Basically how it works is, I award 0.5 points for how many contestants there are left in the game, or 1 above that if there is an odd number. (So, if there are 6 contestants left, I award 3 points, if there are 5 contestants left, I award 3 points.) If you win a daily or an elimination, you get a point. How I fill out the rest of the points for that round is going down a list of people who are still in the game. I start with the winner, then go down the list until it's time to start over again with the winner. You do not get points if you are eliminated that round or not in the game yet. This way I can give credit for competition wins while also taking into account longevity in the game. All ties broken by placement.
Such an irregular season to put through this system given the format. Very funny to see 75% of the winners in tier 3, just because they did not win dailies.
