Guys, since everyone plays the same amount of matches, there is no difference between using a match point system and a win% ranking.
Ransac: Games can end in a tie, but matches can't, simply because the first person to win two games takes the match, any ties in between those games are ignored.
Spidey: Match points are simply the amount of won matches times 3, so they wouldn't influence the current standings. The mentioned abbreviations mean Opponent Match Wins (OMW) and Opponent Game Wins (OGW), which are used in normal tournaments. Come to think of it, they will be different for everyone, since you don't count yourself. This will result in anyone having more points having a lower OMW%, because their opponents will have won less matches. However, it will still be the same for people with the same amount of match points (or match % wins if you like). OGW however might be important, but if you like I'll calculate everything once we're done, and then see what difference they make.
