My concern with tie breaking systems being improvised right now is that it's been established since last tournament that the purpose of recording matches and scores is so that if we find ourselves in this situation, then we can determine a winner without extra matches in which you know each other's strategies.
As it stands, Aaron and Satsuki have been the only ones following that system, and while I'm being cool to you guys telling me your records (because it's not like we'd scam each other,) we regrettably find ourselves in the tie-breaking scenario for which I need that data I asked for. It'd be unfair if we have some bracket match or free for all, and Aaron winds up losing when for all we know he perhaps had the best record.
As it is, I'm waiting to hear from Smiley since he beat Aaron pretty soundly, so I want to know his average pokemon lost per game. If it matches Aaron's average, then we can consider some sort of extra tie-breaker. But as of right now, the main tie-breaker is based on average score per match. And if NateRich also lacks that information, then presumably he could have a match for third with Prismeru?
