Posters who have seen Liza skate live have commented on how small her jumps are and how limited her ice coverage is ---that's why her GOE is low. Her PCS scores are low for the same reason. Liza skated a clean FS, yet her PCS scores were lower than skaters who made mistakes (Sotnikova, Osmond, Gold, Suzuki). Liza's ice coverage was small when she was a junior, but the theory was that was because she was so tiny. However, she's grown quite a bit since then and there's been no improvement in her stroking and her ability to cover the entire ice surface, especially for the FS.
