So after NHK, the rankings based on GP scores are:
Highest GP Score
224.31 1 Rika Kihira
219.71 2 Satoko Miyahara
219.02 3 Elizaveta Tuktamysheva
215.29 4 Alina Zagitova
213.90 5 Kaori Sakamoto
206.41 6 Bradie Tennell
204.20 7 Mai Mihara
203.06 8 Mako Yamashita
198.96 9 MariahBell
198.70 10 Sofia Samodurova
There was a discussion about using average scores of the season to compare the ladies. Well, CS's shouldn't be given the same weight as a GP. I have derived a weighted average based on the ranking points ISU gives for the types of events. A challenger and a GP gives 300 points and 400 points to the winner respectively. This ratio of ranking points is consistent from places 1-5 (
World Standing document-page 5 and
Challenger Series document-page 4). I have used this to derive two weighted averages (slashes added to align the columns):
Weighted average score 1 = Average Challenger score * (300/700) + Average GP score * (400/700)

Based on the weighted averages and the top GP scores, it's clear who the Top 4 are. The gap between Zagitova and Kihira is around 3.5 points based on the weighted averages. So no one is really untouchable, as some have suggested.
As for NHK, Liza Tukt is becoming more consistent with the triple axel and had an almost entirely clean competition. Her PCS is rising and she has room in her layout to put a 3F in to increase her BV (in both programs). Satoko got some UR’s but she now has two strong outings on the GP and got two total scores close to 220. And Rika, coming back from 5th in the SP to having a perfect free skate with 2 3A’s. And 224+ to win gold at her premier GP.
