This tournament would be useful for your improvement due to McMahon system because your games will be more evenly matched.\nThe number of rounds and the top bar could be modified in first round according to the total number of players and the population above the bar.\n\nThings to keep in mind:\n* Use the conditional move feature to speed up the game.\n* No pauses and no vacations are allowed; if any player switch it on, then they will be disqualified without further notice or reminder (unless they have an urgent matter to attend to and give notice to TD).\n* Disqualification will occur automatically by the site if a player loses by timeout.\n* If you find that a player pauses the game, enters vacation mode or has bad behavior, please send a message to the TD.\n* And last but not least: no weekends, just make your move; it’s a tournament, my friend!",
