I believe, Gosviani was sent to Euro at first to stimulate Leonova skate better.Leonova finished the season with 13th place at Worlds with a score 5 points higher than what Gosviani scored at Euros. Gosviani obviously didn't impress the Russian federation with her Euros performance, so they didn't send her to Worlds.
Her result at Euro is not impressive.
Leovova won Gosviani at Final of Russian Cup and because of this earned Worlds.
But Leonova did not impressed RusFed at Worlds.
I don't know who is less (or more) impressive for RusFed - Leonova or Gosviani.
If possible, RusFed will make two GP Events for both. For whom first - it is the question.
