I guess the new rule is no longer in effect, since more than 1 set is being played per match
Oh well then?
I will let vote again tomorrow, if any match isn't finished by tomorrow 12PM GMT, then I'll follow this:
1- more games won; if tied then
2- set won with biggest advantage; if tied then
3- 1st set result
