The scores should have been sorted out after have many points u got and not after the win %. Doesnt make sense that VS is on first place with 4 points....
I think there was a good discussion on this topic last season. It is fair to say that any metric used will be poor, with such a small number of games. Personally, I think this metric gives a good view of a clan's win ratio. But I'd leave this up to the scorekeeper of each division.
You can always create your own custom view if you don't agree with your scorekeeper ;)
