Since these Olympic short program warm-up groups are based on world standings, I would assume that the mens and ladies competitions will be the 5-5-5-5-5-5 groups, and the following skaters would be in the first and second halves based on their current world rankings (and correct me if I'm wrong, but I believe the final two groups (= 10 skaters), are the 10 highest skaters in the standings.)

Ladies, First Half: McCorkell, Phaneuf, Reitmayerova, Nagasu, Makarova, Karademir, Lafuente, Liu, Kwak, Postic, Ziegler, Gimazetdinova, Lee, Jurkiewicz, Pieman

Ladies, Warm-Up Group 4: Korpi, Gedevanishvili, Glebova, Meier, Hecken

Ladies, Warm-Up Groups 5/6: Kim, Kostner, Asada, Lepisto, Rochette, Suzuki, Ando, Leonova, Sebestyen, Flatt
