The award ceremony will take place in the arrival area of each event.

Electronic-timing systems which measure results to the nearest one-one hundredth (1/100) of a second are required. Timing capability to the thousandth (1/1000) of a second may be used to break ties, if available.

A separate backup timing system is required. It may be a separate electronic timing system or a hand timing system and it must have a separate means of communications between the start and finish from that of the primary electronic timing system.

The start gate must be placed in such a way that all starts will initiate the timing measurement. Photo cells on each side of the finish line shall be placed approximately 40 cm above the snow.

If there is a malfunction or failure of the electronic timing system, then the backup timing shall be used for the official time. If the failure is for a single competitor, the timing shall be measured by taking the average difference between the electronic and backup timing of ten other results. These results may be from the five competitors who competed before and the five who competed after the failed result. The start or finish referee must immediately inform the jury when a failure occurs. In the case of failure of both systems, the competitor(s) shall re-run.

A gate is composed of two (2) poles and one panel.

The finish area must be flat and big enough to allow the rider to come to a safe stop from the initial slope of landing a big air or coming out of a course / halfpipe. It was to be fenced off completely and the fences should be laid out in a way there is maximum visibility for officials’ media and spectators.

Group 1: Girls
Group 2: Men 1
Group 3: Men 2

The men can be divided, in different ways:
- if the start list is ready: even and uneven numbers
- if the start list is ready: by splitting the starter field in the middle

by giving out the same amount of uneven and even number and the inscription. (you also can give out different colors of tape or stripes)
The riders have to wear their bibs, the colored stripes or tape which they go at the inscription during the training sessions.

The TS or the Head Judge leads the training and disqualifies if a rider does not respect the training rules.

The jury will announce which judge system will be used during the first TC meeting.

The Judges score each run according to the Overall Impression category. The score of each judge is between 0 and 10 or 0 and 100.

The Separation system allows the riders to evaluate their run by observing how they placed in the four main areas of riding a pipe. The criteria areas of Motion, Rotation, Amplitude and Overall Impression form the basis of the separation system as a form of checks and balances to give the rider the best opportunity to score points in the highest amount of freedom in their run. This system also holds the judges accountable for their specific criteria area with emphasis placed on well balanced judging. With more than four judges, additional judges will judge overall impression.

The rider with the highest overall impression score in the tied run shall be declared the winner. This will hold true in the finals, or in determining the higher ranked place in the qualifications. If the overall impression scores are tied, then compare the individual scores by judging categories. The rider with the greatest number of higher scores shall be declared the winner. If all the above are tied, then the rider with the highest amplitude score shall be declared the winner.

1. The TS is responsible for the Seeded draw of the competitors and placement of the heats in for the start order.

2. Practice session (30 minutes) is set for every two heats during the competition day which includes qualification and finals.

3. After the practice session all competitors will get (1) one warm-up run at start of heat, riders will go in starting order to warm-up.

4. Then competitors will do their (2) two scored runs in their heat running consecutively. Competitors will go off the start list for their heats and will always go in order of start list position.

5. Only the high score will count out of the two runs in the Qualification rounds.

6. Ties will be broken by the ISF Tie-breaking process rule 506.

7. The top six men’s scores and the top 3 women’s scores from each invidual Heat will compose the finals
 
 

Big Jam format for Pre- qualifiers.

1. For use in large field sizes to find the top riders in a Jam format.

2. Size for heats should range from 20-30 riders with 25 optimum.

3. Heats should be no longer than 30 minutes in duration

4. 2 to 3 riders are allowed in the pipe simultaneously…this allows the riders up to 4-5 runs each in the Pre-qualifier.

5. Each judge watches entire jam taking notes on memory board on the bib #'s already listed.

6 Boxes are checked when the judge is impressed by a good run or stand out trick combinations of great difficulty.

7. Total # of boxes checked helps to guide in the selection of the advancing riders of each heat. This will also be used along with the general notes each judges records. At the finish of Heat 1…10-15 minutes is needed for the judges to rank. This is ideal for maintenance time and warm up for the next heat.

8. If you choose 16 riders to advance to the semis and you have 4 heats of30 then you would choose 4 riders from each heat. If you want 32 from the 120 then you can pick 8 from each of the heats.

9. One of the best points of this system is that the Head judge can also closely view the riding and take notes. He is also free to oversee course issues as he is more free to observe the whole deal instead of being cluttered by paper shuffling, sending the next rider etc. At the conclusion of the heat the HJ will have his own ranking with which to compare to the others.

10. To speed up the process at the end of each heat every judge will rank 2 riders more than is needed total for the heat.. EX. the heat has 30 riders and we are to pick 8. The heat is over and each ranks their top 10 riders in order , not 8. Next the HJ uses a simple boxed out sheet of paper and logs the result order of each judge. The extra overlapping amount ensures a speedy decision of who continues and discussion using notes is at a minimum.

11. At this point the HJ checks to see if this corresponds with his personal notes. An additional good which comes from this process is the HJ has seen the riders and has a leg up for the semis and finals when the format becomes criteria based. He is much more aware of the runs which will take place in the remainder of the competition and thus can keep his judges more on track when needed.
 
 

Double-Up Qualification Format using Heats

1) Judge Panels for the Double-Up will consist of no less than (3) three judges on each of the (2) two panels. When using (3) judges the criteria for judging will be all (3) for overall impression.

2) A full panel of (4) four judges using the ISF criteria on each panel is highly recommended. When four judges are used on the panels, the standard ISF criteria system will be used.

3) Heats will be run with a maximum of 25 competitors per heat. Optimum is (20) twenty competitors.

4) Group Training for heats will be (1) one (45) forty-five minute session at start of morning heats and (1) one session before the afternoon heats starts.
 
 

The official result list of the qualification runs shall determine those

competitors who qualified for the final competition.

Heat Format for Finals - Depending on either the Random or Seeded format 20 or 24 men and 10 or 12 women will be in the final.

- A final practice session of both men and women will be held for 30 minutes.

- Then competitors will do their (2) two scored runs in the final heat running consecutively. Competitors will go off the start list in reverse order based on qualification.

- Women shall start first for their two runs consecutively then the men for their two runs.

- Only the high score will count out of the two runs in the Final rounds and this shall be the final standing.

- Ties will be broken by the ISF Tie-breaking process rule 506

- Where the Super Finals is used the top 10 men scores and top 5 women scores will advance to the super finals.

- An approved system that may be utilized by the TS is the cutdown final system. The procedure is of decreasing order: semi final to final to super final which would go from 24 to 12 to 6 riders (men) and 16 to 8 to 4 women from semi-final to final to super final.
 

Jam Format for Super Finals

The Jam format shall take place after the Finals either the same day or held on a separate day.

The Jam format shall consist of 10 men and 5 women riding in the pipe for a 45 Jam session together in which they may take as many runs as they wish but with the minimum of two.

Riders may drop in at random order.

In the Jam only the two highest scores count for the final result.

This jam format will ensure that the riders will be riding to beat the best combined two scores and this will add to the excitement by having the best two scores posted electronically on the scoreboard as well as with the announcer.
 

Jam-System Final

There are different variations of a jam format. Basically the riders can do as many runs as they want within a certain time. Depending on the system all runs will be judged, just a ranking will be given, or certain runs that the rider announces will be judged. Judge system: Overall or Ranking
 

Double-Up Format for Finals using Heats

Possible formula for doing a Double-up criteria in a final format. Using this format where there will be 10 women and 20 men in the finals. To make this formula work properly you will need to use:

1) (2) two full teams of (4) four judges each using the ISF Criteria based judging system.

2) There will be a warm-up period for the women as well as the men before the finals are started.

3) Women will go first with their 4 or 6 runs and having the 2 or 3 best runs count.

4) Men will go next with either 4 or 6 runs and having the 2 or 3 best count accordingly

5)This should take no longer than normal finals and might be even faster and definitely more exciting!.
 

The rider with the highest overall impression score in the tied run shall be declared the winner. This will hold true in the finals, or in determining the higher ranked place in qualifications. If the overall impression Technical merit scores are tied, then compare the individual scores by judging categories. The rider with the greatest number of higher scores shall be declared the winner. If all of the above are tied, then the rider with the highest amplitude score shall be declared the winner. It is the new 236 rule

The amplitude of runs is a very important issue. This is fair due to the fact that it is harder and more spectacular for the viewers to execute a tricks higher, especially if the height is consistent.

A Slopestyle course shall contain a variety of hits with two or more lines through which the competitor may choose to perform. Structures may include at least 2 jumps or fun boxes, 2 quarter pipes, one wave site, and other forms such as rails and ridges that provide the competitors the opportunity to display their freestyle talents. The course may be designed for a minimum run time of 40 seconds and a maximum run time of 90 seconds for the average competitor.

The qualification round may be organized the same day as the final round. The start order shall be announced during the halfpipe TC meeting. The qualification round may be organized in different formats as in rule 512.

The finale round may be organized in different formats as in rule 513.

The official result list from the 1st qualification run shall determine the final ranking for competitors not qualified for the 2nd run. The official result list from the 2nd qualification run shall determine the final ranking for non-finalists. The competitors who DNS, DSQ, or DNF during the second run will be ranked according to their result of the first run. For the finalists, only the combined scores from the final shall determine the final ranking . The finalists who DNS, DSQ, or DNF will be ranked according to their previous results.

The amplitude of runs is a very important issue. This is fair due to the fact that it is harder and more spectacular for the viewers to execute a tricks higher, especially if thethe hight is consitent.

The run’s overall precision will be evaluated, including the execution of the run and the routine attempted. Style will not be considered, but the precise nature of the run in relation to maneuvers attempted, both individually and as a sequence will be evaluated. The overall composition of the run is the important as the evaluation of the sequences of tricks , the amount of risk in the routine and the progression of new material in the pipe and variety of runs. Falls will be taken into consideration.

ISF officials must approve the competition site, otherwise the ISF does not recognize the event and any relation with the ISF is null and void.

Gap: 40ft from end of kicker to drop-off of landing

Landing: 80ft of 30%

Run-out: 120ft of tapered from 30% to 10%

As always, the surrounding area needs to be secure with fencing and with a wide enough area to make sure the venue is secure. Additional points would be blowing enough snow to make the kicker big which insures safety as the riders will be traveling of the Gap and not landing on it. It is also important to note that the landing need not be more than 30% – to 32 % as any more steep will cause the riders to jet ski out when they land. Also the kicker needs to be wide enough to accommodate spins of all types and account for drift in the takeoff and the landing.
 

The start area shall permit the competitor to drop into the course. The drop in allows the rider to have the correct speed for the jump.

The landing has to have the correct angle to accommodate both flips and spins.

The finish area must be flat and big enough to allow the rider to come to a safe stop from the initial slope of landing a big air. It was to be fenced off completely and the fences should be laid out in a way there is maximum visibility for officials’ media and spectators.

At least one training session for all competitors is mandatory. It is recommended to allow every rider to have at least 4 training jumps. There will be a starter at training to regulate the flow of the riders. The training shall be divided into training groups if there are more than 30 competitors.

The main emphasis is on the landing but the take off plays an important role in the whole trick too. Basically a trick can’t be executed very well if the take off or the landing is bad. A slam can lead into a big deduction. Credit should be given for small handtouches or light bails after really extremely hard tricks.

ISF officials must approve the competition site, otherwise the ISF does not recognize the event and any relation with the ISF is null and void.

All World Ranking lists, points, top rider quotas and other calculations will be based on weeks that start at 00:01 hrs Monday and finish at 23:59 Sunday.

Two sets of points are attributed at a Pro competition, (calculated according to Rules 1001 through 1004, and Rule1015). Both will be entered into the competitor's record. Firstly as regular ISF points, then as Prize Money points.

Each riders attributed regular ISF points shall remain valid for 52 weeks from the week number of the competition.

All riders will appear on the world combined ranking list. The total points of each rider in the combined shall be calculated by the following formula: Combined points = ((GS points+DU points)/2)+HP points + BX points.

These ISF World Rankings shall be available to any race organizer or ISF member. They may also be available on the Internet Web site at http://snowboardranking.com/

The ISF World Rankings shall remain valid and in use until Thursday of each week when the new ISF World Rankings shall be used. If the new ISF World Rankings are unattainable the most recent lists shall be used with the proviso that all points attribution be clearly marked "unofficial" and are subject to change.

National Ranking lists may be compiled using either the normal ISF criteria, or other criteria that the individual National Snowboard Associations may require from time to time.

Maximum points calculations fee payable by the National Snowboard Associations:

Continental Open US$100 per discipline
Value 6 Nationals US$ 75 per discipline

On receipt of a medical certificate at the ISF World Rankings Office, signed by a medical doctor, the riders rank (frozen status) shall be determined from that weeks official ranking list for each discipline. If the medical certificate does not have a probable recovery date included then it shall automatically expire after two weeks unless renewed.

If the rider has not resumed racing after 52 weeks all ranks and points shall be dropped.

During the period of the injury the rider shall appear on all ranking lists in frozen status, except that a "*" shall appear alongside the surname. The riders points will probably not correspond to the rank shown.

When an injured rider's medical certificate recovery date has expired, or the rider has declared him/herself recovered, or the rider starts in a competition the "*" shall be replaced by a "+" in all disciplines.

The recovered rider shall remain at the frozen status position in the discipline ranking list until:

2. 52 weeks have elapsed from when the rider restarted racing

3. The rider earns points that equals or improves his/her rank

4. The rider elects to abandon his/her frozen rank status
 

When anyone of the above four points have occurred, in the separate disciplines; the "+" shall be removed from the surname and the rider's points and position in the ranking list shall be calculated as normal.
 

When the official ranking lists are used for:

1. Seeding purposes to determine start position then all surnames followed by a "*" shall be ignored but if followed by a "+" shall be included.

2. Point attribution (value of a race), then all surnames followed by a "*" shall be ignored but if followed by "+" shall be included when counting the top riders starting.

3. Determining eligibility for entering a future event then all surnames followed by a "*" shall be ignored but if followed by a "+" shall be included.

4. Determining the ISF World Tour and ISF Tour ranking winners all Surnames followed by a "*" or a "+" shall be ignored.

5. Determining the next seasons housing reductions all surnames followed by a "*" or a "+" shall be ignored.
