V. PERSONNEL 5.01 Tournament Director A.Appointment I V. WORLD CHAMPIONSHIPS remaining two players both advance to the semi-finals with the winner of  their head-to-head match advancing as the group winner. Comment 6: 3 players have 2 wins and the other player has 0 wins. The  player with 0 wins is eliminated. Of the 3 players with 2 wins, all have  played 3 matches and all 3 have set won-loss records of 5-4 (55.56%).  In this case, we move to % of games won. The % of games won breaks  down like this: 44-40 for 52.38%, 45-43 for 51.14% and 44-43 for 50.57%.  This produces a 1, 2 and 3 order of the group and the number 1 player in  % of games won is the group winner while the player finishing 2nd in %  of games won advances to the semi-finals as the group runner-up. The  player with the 3rd best % of games won is eliminated. e) In applying the tie-breaking procedures, a conduct default or retirement shall  count as a straight-set win or loss. However, games won or lost in matches  with the defaulting or retiring player shall not be counted in the percentage  of games won. A player who retires during the round robin because of illness  or injury may continue in the competition if it is approved by the tournament  Doctor. Comment: This prevents a scenario where a player knows he only needs to  win 1 set to qualify for the semi-finals from retiring once he has won a set. f)  Any player who is defaulted pursuant to the ATP Code during the round robin  competition shall be defaulted from all other matches in the Championship  and ATP default provisions shall apply, except for the following circumstanc - es: i) The loss of physical condition; or ii) Dress and Equipment. g) Any player who withdraws from any round robin match after the first round  shall not be eligible for the single elimination competition.
