In order to increase safety, ease crowding and allow for growth, all skaters will be placed in waves determined by past performances. Registrants with no previous NSIM history must choose their wave (one-time basis only). Participants with multiple finishes will receive wave placement based on their most forward wave qualification performance from the last three events. In the event of a three or more year ‘break in participation’ in the NSIM, a skater will be placed in their most recently qualified for wave. Wave placement will be made on a first received, first placed basis.
