According to Liquipedia (not sure if this event use this rule or not):
3-way tie:
- Head-to-head Match Series
- Teams with two matchup head-to-head advantage automatically receives first of the group. Tie-breakers for the remaining two teams are determined using the above head-to-head tiebreaker process.
- If no team has a two matchup head-to-head advantage (all Teams are 1-1 head-to-head), then proceed to next step of the 3-way tie-breaker process.
- Map differential
- Round differential
- Round Wins on Opponent's Map Pick
If KIMMY KITTENS loses to NAOS, there will be 3-way tie between KK, FS, RRQ.A.
The thing is that I'm not sure what matchup h2h advantage means. If we count the match win, the result should be (KK: 2-0, FS: 0-2, RRQ.A: 1-1). If this is the case, KK will qualify as the first team, then RRQ.A will qualify since they won FS. If I understood this correctly, it doesn't matter what the map diff or round diff will be, RRQ.A will always be over FS if KK loses
