Quote from jaybird13 >> I made a thread about this a couple of weeks ago because I saw the horrible win % of the top ranked players.

Someone mentioned then that the top 100 is sorted by total coins won through seasons. Not sure if that's accurate, but it would make sense. 

 I think it goes far beyond total coins earned. Wouldn't doubt that's part of the formula, but I do doubt it's solely based upon coin accrual.
