Makarova landed only two triples in her RN free skate. Two of her triples were downgraded and she got UR on two more. She attempts only one 3F in the program and she lands it only 50% of the time. She doesn't always go for the 3t+3t either, and when she does, it can get downgraded to a 3/2 as it did at RN.
With that jump content and the number of downgrades and URs, I doubt she could finish even top 10 at US Nationals. She certainly wouldn't get PCS scores in the 8s as she did in Russia.
I believe that the only reason she finished 4th in Russia with that FS is the Russian federation had to send her to Euros because she is one of only 5 age-eligible skaters (Leonova, Makarova, Korobeynikova, Biryukova, Shelepen) and she finished ahead of three of them on the strength of her fine SP. It wouldn't have looked good to send her if she finished way back in the pack, especially since Ksenia and Alena Leonova are the only skaters who have a strong senior competition record, with good finishes at previous Euros, Worlds and Olympics.
