Logically there are many possibilities, but here, let's think that the next medals for the following ladies are fixed.
Mao: Gold or Silver
Meissner: Silver or Gold
These three go to Torino for sure, so three more slots.
Ando may medal again but the color unsure, sums up to 28 or 26 or 24 GP points.
Silver is enough for her. If Bronze, it'll depend on Meier's score at NHK.
Rochette meets Nakano again and if N beats R, Nakano goes to Torino with 26 points.
If R beats N, both is almost certain to go to Torino when Ando wins NHK.
If Kostner wins NHK, either one of R or N goes.
Kostner may medal again but the color unsure, sums up to 26 or 24 or 22 GP points.
If Gold she's in, which probably makes Zhang out because of tie-breaking scores.
If Silver, which probably means Ando's Gold, makes both Caros 24 points so Zhang gets a chance when Rochette is out.
If K is Silver and A is Bronze, Zhang won't come out of tie-break.
So it's only when Ando winning the NHK and Nakano beating Rochette both happen that Zhang will be in Torino.
