To decide our final double-promotions, the 3-way head-to-head tie between Joe Howe, Hasdrubal, and Mirage was split using the 'overall win-loss ratio' where the total wins of all the players they had beaten was compared to the total wins of all the players they had lost against. Joe had beaten more of the top players, and so came out on top, with Hasdrubal taking second to gain the final double-promotion.
Is there an explanation for this in this thread? I expected some quick 3-way tournament, instead.
