And, for instance, 4 kyu and below means not higher than 3.1 kyu</li>\n</ol>\n\n<h2>Attention</h2>\n\n<h3>Speed and Time-out</h3>\n\nKeep in mind that the avg speed of one game is about <u>3 moves per calendar day (or 12 hrs of your clock time)</u> per player. Since the Round Robin will activate several games simultaneously, for a match with five players, the avg speed times 4. <strong>To avoid losing by time out</strong>, the safe way is to play a little bit faster than the avg speed. \n\nLoss by time out will be labeled as \"disqualified\" on the table by OGS' program.\n\nLoss by time out will affect your reputation in this Match system.\n\n<h2>Tips</h2>\n\n<ul>\n <li>Use Plan Conditional Moves to speed up</li>\n <li>To pay more attention to the progress of this tournament (use filter "Game" in Active Games list on the Home page or Profile page, or press "Ctrl+F" to find the key strings "<strong>Mid-</strong>" )</li>\n</ul>\n\n<hr />\n\n<h3>Ref</h3>\n\n<ul>\n\t<li><a href=\"https://online-go.com/tournament/101297\">Previous tournament</a></li>\n\t<li><a href=\"https://online-go.com/group/12936\">About the <strong>Mid-speed</strong> Group</a></li>\n</ul>",
