It's different to compete domestically and compete on the biggest world stage with a task of perfect or close to perfect skate and bringing 3 spots back home.
I wouldn't call Muravieva or Petrosian steely competitors for that matter.
Whoever is sent will for sure get 2 spots (for placing in top 10), but getting gold or silver to claim 3 spots will for sure be a psychological burden for the chosen one.
I disagree.
Here are my points:
First let's be clear that not a single person at worlds was perfect.
No perfection is needed for any of the Russians to win considering all 3 medalists had errors. 2 with major errors (Gold, and Bronze).
1st fact - Two falls on regular triples = a bronze medal this year
2nd fact - A popped triple and under rotations on triples = a gold medal as well
Not a single Russian lady at the top needs to be perfect when this is a regular issue internationally. The field is not tough by Russian Lady standards. Anna needed to be tough against Aliona, Trusova, Kami, Maiia, etc who all had ultra-c and were her teammates. Being the only Russian there and most likely guaranteed to have the highest tech would be a relief with no other skater at your level technically.
In Muravieva's defense with her skills, she can go back to her junior level and win with only triples. She is that strong (at least prior to her injury).
She won all her GP's her very first international season in Juniors under a lot of pressure being the last to go and deliver back to back clean skates in the short and the free for a GP final spot.
She is 100% steely without ultra-c which with her level of PCS would be an easy podium win internationally.
Being the only Russian skater there she does not have to worry about doing multiple risky quads or triple axels. Muravieva started regressing terribly after introducing ultra-c and getting injured. Most of her skates without it are mainly always clean even under heavy pressure. With ultra-c she's 50/50.
She is absolutely not Shcherbakova. No one is. Maybe RUSFED will pay Anna top dollar to return after fully healing and re-gain the 3 spots in one go since she's the most reliable (though I am not sure if Anna would be motivated to return. She said she's not retiring, but what would be the motivation? Another olympic medal she has already won? ). Though internationally it's not an all out battle of ultra-c like it is in Russia. Anna is not needed to win spots. If another amazing and chaotic Trusova level skater shows up internationally then maybe they can push Anna to come back for another Olympic level nerves of steel mental strength miracle gold medal win against 5 or more unstable quads, but since that is not the case Anna can relax doing ice shows. The reigning olympic champion does not need to be summoned as a crisis of that level has not yet happened.
Any of the girls (barring Akateva and Alina) at the top of the Russian field at Nationals could win 3 spots if two falls on triple jumps = a bronze medal. It's the Worlds standard for bronze. The ask isn't hard. There is zero need to be mentally tough when the best you need to compete against will fall on two triples or pop their triples which is enough for bronze as well as gold.
There are no new competitors with surprise stable ultra-c to fear. Tuk would have the easiest wins this season without breaking a sweat, and if the field continues the same as it did this season there is no need to be mentally tough. Unless Mao bypasses the rules the girls are good to go in seniors.
Adeliia does not fall on triples unless injured like she was this season. Prior to this season's injury she seldom fell on triples and in terms of triples was without a doubt reliable. I'll have to see how she is next season after acquiring all these jumps that she has (4T, 4S, 4F, 4Lo, 3A) and healing from her last injury. We'll see if she falls on her triples after healing next season (unless she's injured again). Adeliia with a triple axel would have had short program advantage (she only fell on 3A once this entire season which is more stable than all of international attempts) and unless she bombs the free by falling on all her jumps she would easily earn 3 spots based on this year's results (2 falls = a bronze medal). With two falls from nationals, a similar tech score, and a low level 60 in PCS Adeliia would still beat everyone internationally in a free skate with 155+ points to lead. No perfection needed.
Barely anyone internationally is stable (not even with ultra-c just triples. It is not at all a tough ask). It's mainly the Russian ladies that are tough to beat in domestic comps that you need the mental toughness for. They'll win 3 spots easily by the current international standard and current level of using PCS as a crutch to push unclean skaters ahead of clean skaters. No perfection needed as that's the standard shown at Worlds or else the more "perfect" skaters would have been on podium.
With everyone at the same level if we have a low 64 in PCS skater vs a high 73 skater, the skater with a 64 will be destroyed. But against a top Russian lady with the tech of Adeliia a very low 60 is enough to easily win gold (with falls) against a 73 PCS skater with average tech.
If Haein or Kaori come out with a triple axel or quad with how high they get scored now then maybe yes the Russian Ladies will need that Anna level mental toughness to secure a gold medal for 3 spots. Until then it shouldn't be a tough ask because the field is nowhere near tough by Russian ladies standard.
The judges can of course give the Russian ladies 20's, 30's, and 40's in PCS to plunge them into darkness, but that would be ridiculously obvious sabotage. Low 60's in PCS is enough for a guaranteed gold win for tech rich Russian ladies even with 2 ultra-c falls (not even clean).
Muravieva easily scored 72 - 73 her very first junior international season in the short while it took years for some of the other international ladies to reach this (like the silver medalist). She is that good. With only triples she would be fine, but for a guaranteed gold win she'd at least jump one 3A in the short. If she can jump that triple axel 10 times in a row at that jumping comp with her fresh injury she should be fine by the time they are allowed back and she's healed (if she's still skating by then).
