NS vs VLT probability

NS lose
1 VLT
2 Naos
3 NS

NS win 2-1
1 Naos (same map diff, better round diff compared to VLT)
2 VLT (better map diff compared to NS)
3 NS

NS win 2-0
1 Naos (better map diff compared to NS and VLT)
2 NS (if NS win with +9 round diff, such as 13-8 and 13-9)
3 VLT
VLT just need to win a map or lose both with small round diff

its so simple like this idk why people are so confused

O

there is one more scenario , if VLT lose 13-4 13-5 (basically VLT get less then 13 rounds in both maps ) then ,

1.NS
2.VLT
3.NAOS

no, the other thread is right. can you show me where in the tiebreaker rules that “map diff” is a tiebreaker?
