The organizers invite their participants to any indoor activity and practice the sequences as much as they want. Then they submit the highest scores and videos at any time and until a week before the end of the month at the latest.

Each group then follows up with more scores and videos until the last day of the month. The groups have the opportunity to improve the scores with new videos after new tunnel sessions after the first scores have been posted and at any time.

Teams and any lineups of individuals may also submit videos for their ICL group after their own separate flying sessions to improve previous scores.

Lineup Limitations:
AAA - AA: Always open for everybody
A - Rookie RRR: 1 Player coach
Rookie RR - Rookie R: Up to 2 Player coaches

The lineups are flexible, and the organizer may put them together according to common sense, based on experiences and skills. Participants may post two scores for any two neighboring categories. Player coaches are not restricted to two categories.

Player coach definition: A person who has scored 13+ average in AAA at any outdoor meet or 17+ average in AAA at any tunnel meet.

Category Limitations:
AAA - AA: Always open for everybody
A - Rookie RRR - Rookie RR - Rookie R: Every competitor who scores 25+ twice is required to move up to the next category.

The "move up rule" applies to scores for this indoor competition only. If participants score a 25-pointer or higher twice in the same category, it shows that they are too good for the same category and have to move up.

Scoring Limitations:
The two lower Rookie Class sequences (R - RR) are limited to scores of up to 25 points. Higher scores will be posted only for journalistic purposes, while 25 points will be posted on the leaderboard and be added to the ICL total of the according month.

Working Time:
Teams may enter the tunnel and establish all grips for their first formation. Timing begins with the break of the first formation, and scoring includes the first formation. Scoring and deductions follow standard competition format and end at the traditional 35 second mark.
