The newly passed FINA Degree of Difficulty Tables will apply to the 2013 Winter National Championships. The FINA Degree of Difficulty Table (available here) was determined at the FINA Congress, which was recently held in conjunction with the FINA World Championships. This table will go into effect on October 1, 2013 and will therefore be utilized at the 2013 Winter National Championships.
Please note that in the Qualification Procedure, a minimum degree of difficulty must be met in order to participate at the 2013 Winter Nationals. This minimum degree of difficulty will be determined using the NEW Degree of Difficulty Table.
