Skating both segments of the TE did not burn out Lipnitskaia: the media onslaught of the home TE gold did, and since Lipnitskaia skated both segments, there was no other Russian woman to share the attention, interviews, media following her every step, etc. The Ladies individual event was at the end of the OWG, and if Lipnitskaia had had a few days to cool off from the TE excitement and the rest of the time to concentrate on the individual event, she would have, as a 15-year-old, been just fine to compete a week later.
Sotnikova was pissed off that she did not get to skate in the TE, and it fueled her determination in the individual event. I haven't followed Valieva long enough to know how she would deal with a Chen-like poor showing or what drives her. But whether or not Women are split in the TE or Valieva skates both segments, you know that Trusova and/or Shcherbakova are going to come out fighting with that extra incentive, if they're left off the TE, and, especially, if Russia wins an expected gold.
