The tiebreaker for a 2-way tie is:
" For ties involving exactly 2 players, compare their head-to-head win rates within the current stage."
The meaning was clear in Stage 1. What does it mean now in Stage 2? I assume we look at only the games in which both players participated. But is it then:
a) Most wins across these games?
b) Most points?
c) Most higher placed finishes (like in eg. Intermezzo)
d) Something else?
