For the 2022 US Nationals Scoring, we’re requesting PDF copies of Freestyles, the same as for Regional’s.  We will be preparing our scoring system in advance, and this saves time on site if we can get as many Free Programs loaded as possible before the start of Nationals. Hard copies are still primary, however soft copies will assist us in clipboard preparation.
