afternoon round robin. Player plays against everyone else in the same group.
The winner of a group will be guaranteed to play in a more challenging group next
week.

DavidR and aDong will decide the group one winner. DavidR defeated aDong
3:0, so DavidR won the first place in the top group.
 aDong won the second place. He did not play much ping pong for the past three
weeks, but he came back strong and almost beat everyone.
Group 2

break the tie. Shawn won 91 points and lost 86 points. Carlton won 89 points
and lost 98 points. ABC won 92 points and lost 88 points. So Shawn’s win/loss
ratio of points is 1.058 higher than ABC’s 1.045, Shawn won the second place.
