Scoring
By default scoring is based on number of Game Wins over the entire tournament. However, individual Rounds may Reset the scores, so that the scoring will begin again from that round. When the first round of the Tournament is seeded by score, the player's score at time of joining the tournament is used in that round only.
Ties in Score shall be broken by the following rules, applied in order:
Percentage of wins in the tournament as a whole
The cumulative number of Game rounds required to win the games they have won in the tournament (since the last point reset, or the start of the tournament if no point reset has occurred). Note: winning in less rounds is better.
The order in which the player joined the tournament (first player to join wins)
