The Snowboarding Live Scoring System, or SLS, is a judging system that has evolved over the past 10 years. It was launched successfully during the TTR 6Star Arctic Challenge Slopestyle, held in Oslo in 2010, and the first Halfpipe, at the 5Star BGOS in New Zealand in 2010.
The SLS system has a focus on individual tricks combined with overall impression. There are dedicated Trick judges and OI (Overall Impression) judges. The combined result of Trick and OI scores gives:
The SLS system has a transparent scoring path showing how the run result was achieved, a result that can be compared trick by trick, from run to run.
Each TRICK is judged by teams of two. They focus on just one feature in the Slopestyle course, and one hit in the Halfpipe. Judges will concentrate their judging values on Amplitude, Difficulty and Execution.
Each OI judge focuses on the overall impact of the run over the entire course. Judges will concentrate their judging values on Variation, Style and Combinations.
In Slopestyle, the SLS system allocates two dedicated judges per obstacle (rails may be judged as a single obstacle or a set). Each specific obstacle (or rail set) is scored by two judges. Each feature will have a set value. Based on the maximum value for each feature, a trick score is then calculated.
The individual scores are then added up for a Total Trick score. For the OI score, two additional judges are dedicated to focusing solely on the usage and composition of the slopestyle run. The two OI scores are then averaged for a Total OI score. Total Trick + Total OI scores provide a Run score, which defines a rider’s final position in the event.
In Halfpipe, the SLS system allocates two dedicated judges per hit. Two judges score each specific hit. All hits have the same value assigned. Based on the maximum value of the hit, a trick score is calculated. Only the 4 best individual Trick scores are kept and then added up for a Total Trick score. For the Flow Score, two additional judges are dedicated to focusing solely on the usage and composition of the halfpipe run. Flow judges will take into account all tricks beyond the 4 top scoring hits that are scored by the judges as well as any insecurity including falls. The two OI scores are averaged thus :
Total Trick + Total OI score results makes a Run score, which defines a rider’s final position in the event ranking.
Trick and OI judges will score on a 0 -100 scale. The Run Score is the sum of the total Trick and OI score combined and will be communicated as a common 0 – 100 points value.
The rationale for utilizing the Overall Impression judging System is to take advantage of the spontaneous flow of the riders competing. It gives qualified high level judges the ability within the OI system to judge more effectively by taking the whole run into consideration rather than a specific criteria area. Beginners and intermediate riders can use the knowledge gathered from the criteria system categories of, motion, rotation, amplitude and OI to better understand their run and develop accordingly.
However with the expert rider, the criteria system has a drawback, the closed nature of the system forcing the rider into primarily considering maximising points score rather than taking risks, thus, stifling innovation – and progression.
The OI judges evaluate all phases of all the tricks. The judges will score the run by evaluating the run’s overall precision, which includes the execution of the run and the routine attempted no matter how the run is setup in its formation. The emphasis of the OI judging system is to evaluate the whole run with all elements of the criteria combined but not placing a major emphasis on any facet but rather evaluating what makes the most dynamic run in the contest at the specific moment. Therefore the main emphasis is the sequences of tricks, the amount of risk in the routine and the progression of new material presented.
The overall impression judge evaluates the specific tricks individually and as a sequence, looking at:
What is looked for is the highest level of progression, for example how a run is done perhaps with only one straight air and five inverted rotations or an all switch run that is done with maximum technical skill, or a run that has a new move, or sequences of moves that pushes snowboard progression forward.
The OI judge must recognize subtle,as well as obvious changes in a routine, to determine what makes it more difficult, as well as what tricks are being performed to the highest standard for that specific contest. As always the OI judge must take falls into consideration.
Focus then is as follows for the judges:
One goal of the World Snowboard Tour goal is to provide a platform for consistent judging throughout the World Snowboard Tour events and throughout the different star levels, and for that purpose we have developed and implemented a judge certification system. Certification, which is valid for two years, will be granted at the end of the judging clinics based on attendance, previous experience and judging skill. The levels of certification are as follows:
The goal of the TTR/WSF Judge Education Sessions are to create a uniform judging platform that spans all levels of snowboarding competition. For further info regarding the TTR/WSF Judge Education Sessions and dates, please get in touch with TTR Judge Director Sandy McDonald: email@example.com
