I think her free program is kind of common, while her short is very very good. That's why she received lower, although with not much, PCS than Panenkova
It would be silly to start promoting Kostornaya against Panenkova. Kostornaya is like a child in comparison, pretty, polished but a child, and it is very obvious she will grow quite a bit, her legs will get longer and bigger, and her jumps are not perfect. Panenkova, in contrast, is already almost fully grown both physically and in height (her mother and aunt are short) and she has unarguably the highest and strongest jumps with great landings and all rippons. Also, it is better to have lip than flutz. Daria, in contrast, is very independent and more mature as person, having a whole season of unmistakable competitions behind.
