Not so fast. Today was just a fluke -- overrotating a triple because intensive quad training over the past days, after recovering from injury. Trusova now has correct jumping technique (which is extremely important), and has shown massive improvements in skating skills and artistry. Barring circumstances such as illness/injury, she and Liza T. have the highest probability of making the Olympic team, as their correct technique makes them resilient to fluctuations in body mass and center of gravity.
Shcherbaova has been showing visible signs that the faulty technique relying on upper-body induced torque is starting to fail her, in the same way it failed Zagitova, Medvedeva, and Lipnitskaya in the past. Valieva also has major flaws in her technique, most visible in her weird axis position in the air, the wonky landings, and the wobbles in attaching a second jump to a combination. The Russian Cup Final amply exposed those flaws. As for the other girls, only Khromyk has quads, and they are not fully rotated or stable at all.
So the Olympic team will most probably be Sasha T., Liza T., and whichever third girl manages to be in top form next season.
