You are correct. Like I commented in another thread, its pretty obvious the last few years the Japanese federation doesn't support Mai or Wakaba. They prefer Satoko, Rika and Kaori this season. Last year for example even the Russian commentator(Lipnitskya) at Cup of China was saying how she couldn't understand why Japanese federation doesn't support Higuchi.I had only the results of worlds in mind and knew that Wakaba received 29 PCS for a clean free skate. Since scores usually go up through the season and not drop, i thought she got less at the start of the season. Same for her FS PCS which was 59 for a program that was not an epic bombing. I didn't think she was at 65 at her first GP.
If JSF doesn't do even a bit of politicking now, then some girls have luck, and what a luck.
Satoko mostly have competitions with no UR calls or max 3 calls, while she can receive much much more. And she good GOEs. Kaori now is getting 32 PCS with two falls in SP, Rika at her senior debut is at 32 with a fall. While Mai have to be perfect to get those 32 PCS.
And about refinement, i would rather say that Rika has a better choreographed free skate than Wakaba in 2016. And Wakaba's 2016 SP beats Rika's juniorish SP.
I think JSF doesn't have politicking skills of RUSfed or Canadian fed who can up by 15 points the score of their girls in a blink of eye, but she maybe can make easier the life of some girls.
