JSF announcement as of June 12, rough translation by myself
"The Olympics team would be selected as follows.
1. Skater(s) who finish off the highest rank in the GPF within 3rd place is determined as an Olympics qualifier.
2. The winner in the Nationals would
basically be determined as a qualifier.
3. The remaning slot would be selected from the following, taking into account the acquired points, the conditions/performance, and the World Standings, at the end of the Nationals event;
a) skater(s) within 3rd place at the Nationals
b) GPF participant(s)
c) skater(s) within the top 3rd Japanese skaters rankings in the ISU World Ranking System.
However, a skater(s) who do not fall into any of the categories above due to an injury
etc. during the earlier half of the season, but has acheived finishing within the 6th place in the past World Championships event, can be included in the selection roster,
taking into account the skaters' condition towards the Olympics event. "
Take a look at the slanted wordings- Mao can be easily included the Olympics roster without bending the rules even if she finishes off the podium in the Nationals.
The above is NOT a perfect translation.
