Another thing about the SGP. Skaters just can't "do the GP". They have to be in a position to be invited to GP events by other hosts, which means they have to have accumulated enough ISU points to be in the top 24 on ISU World Rankings OR be in the top 24 on the Seasons Best list. The only way for young skaters to do either is to medal on the JGP AND/OR medal at the JGP/JW. Polina couldn't have done the GP this past season because she had NO ISU points at the end of the 2012-2013 season as she hadn't done the JGP yet at that point and hadn't been sent to 2013 JW.
