Chen´s way of upper-body movements, carrying her arms and melting into music is world-class.

What she does from 2:03 on and especially at 4:11 is just beautifully refined and meaningful at the same time.
I just compared it to the rusnats videos and although the emphasis there is on "refinement" to conceal the lack of expressiveness in youngsters while preferring them over more expressive competitors, Chen´s movements are imo an example of what refinement in skating is about. Never rushed or just positions, but deliberately while naturally elegant.
Nonetheless, I don´t think it´s fair nor a good idea to send her to worlds.
To be honest, I remembered Glenn to be a more artistic skater from former nationals, but if someone finishes higher at nats plus has harder tec content, he/she should be sent to worlds.
And world-class body-expression, or even step-sequences, transitions and so on ... won´t win a medal at international competitions.
The rule is jump-jump-jump and make up for the rest in politics.
That´s why russians are sacrificing the artistic component (and I´m not blaming them, cause this kind of influencing, managing and judging competitions is a long time tradition in FS), even the more as PCS are sort of a second TES marks section rather than real program components, so that an strong PCS skater will even on the PCS site be outraged by a strong TES skater.
So, to me there is no sense in sending someone artistically strong as long as she has no 3A perspective (and not even a 3-3).
If the feds would stop to play political games on the international stage, they could stop to act according to these games rules on the national stage, judge what is put on the ice and sent the successors.
Finally, there would be real competitions.
