Each country designates 4-6 stackers to be on their country's International Challenge team. Any 4 of those stackers can compete in each International Challenge race. The team coach determines which 4 stackers stack in each race.
The teams time for each race is compared to the other teams time for each race and the team with the fastest time wins that race. Best two out of three races wins the match. The winner of the match progresses in the double elimination bracket to race the next team. Double elimination brackets are not normally seeded, however for this event we try to evenly distribute countries so the top teams do not meet each other in the first round) Brackets are published and updated in real time on the WSSA website. Stackers are expected to watch the bracket to see if they advance and when they compete. This is especially important given that matches will often be between teams in different regions, so a team won’t know if it wins a match until the other region completes its attempts for that match.
On Zoom with a live judge, each of the 4 stackers racing stacks the Cycle one by one. All four stackers times are added together to get the team’s time for that race. If one or more stackers scratch, the team gets a scratch for that race. The team does this three times and those are that team’s three times for that match.
Individual HTH (replaces Age Division HTH)
This event is run with a double elimination bracket, which is seeded randomly. The size of the bracket will be based on the number of competitors and will be published and updated in real time on the WSSA website. Stackers are expected to stay on the Zoom call and watch the bracket so they know when their next race is. Stackers will forfeit races if they are not present when their race begins.
Each match consists of best 2 out of 3 Cycles. Stackers alternate within each match. The stacker with the fastest prelim time gets to decide if they want to go first or second. Example: Lisa’s best Cycle prelim was 9.765 and Kailey’s was 7.854. Kailey gets to decide if she wants to go first or second.
The brackets for each age division are run within each region and are run from start to finish in one Zoom session. To determine the winner of all three regions, the winner of each bracket does an additional 3 Cycles. Those times are compared to the bracket winners for each age division in the other regions as a virtual StackOut. Best 2 out of 3 races is the overall winner for that age division.
