Let me retract my point and agree instead with FistOfLife.

I was wrong. We can save trying to come up with an intelligent way to gauge skill in a solo ELO thing for a different discussion (one we've held a hundred times because Fist and I, along with many others, can't stand the ranking system).

If the goal of Clan Rankings, is to create clan war activity, it's doing a great job. They just need a harsher penalty for losing, so a tighter algorithm basically.
