Absolutely. It's clear that good technical performances magically raise PCS scores quite often without good reason. So Tech comes first for Mirai. She's been around long enough that the judges will raise her PCS if she lands that axel AND other triples.
She also has to show some connection with the music. So far there has been none, either in terms of body movement or facial expression.
Mirai landed all her jumps cleanly in the FS at 4CC 2017 and still got PCS scores only in the 7s, while Gabby Daleman had two mistakes and got all 8s.
The judges want more than just a technical exercise. They want a performance. Mirai executes her elements, but she doesn't perform her program---and music is an integral part of that program.
