|Spiral Sequences are written like this: SpSq with a number from 0 to 4 following that indicates its Level. The complete Scale of Values for Spiral Sequences with Grades of Execution for each Level can be found in ISU Communication 1494.
The following definitions, clarifications and more can be found in the ISU Technical Panel Handbook- Singles Skating, on the ISU website. It is difficult to find.

A Spiral is a position with one blade on the ice and the free leg (including knee and foot) higher than the hip level. Spiral positions are classified according to the skating leg (right, left), edge (outside, inside), direction (forward, backward) and position of the free leg (backward, forward, sideways).
Spiral Position on a flat
Such a position is counted as one of the first 3 attempted positions, but no Level features will be given for this position. If a skater starts a spiral position this way and then goes on an edge, the counting for the length of the spiral starts only when the skater is on the edge.
Losing the Edge
When during the spiral position the skater loses the edge, goes on a flat or to the other edge without intending to change the edge this is considered the end of the concerned spiral position. If the skater after that comes back to the allowed edge this continuation should be ignored and not counted as a new position by the Technical Panel.
Free Leg Drops
When the free leg drops at the hip level (or lower), this is considered the end of the concerned spiral position. If the free leg, after the drop, comes back to the allowed position (higher than the hip level) this continuation should be ignored and not counted as a new position by the Technical panel.
Spiral Sequence Definition
There must be at least two spiral positions with the free leg (including knee and foot) higher than the hip level each held for a minimum of 3 seconds
Duration of Position
All positions or feature in a Spiral Sequence must be performed for a minimum of 3 seconds to achieve the appropriate feature. If this minimum hold is not fulfilled the position will not count for Level features but will count in the number of position attempts.
Spiral Sequence Levels
Please consult ISU Communication 1557 for complete details
2 of the following Features required for Level 2, 3 for Level 3, 4 for Level 4
L& R, I & O, B & F mandatory for Levels 3-4
1) A difficult variation of position
2) A difficult variation of position on a different foot significantly different from the 1st variation
3) Change of edge in a spiral
4) Unsupported change of free leg position or direction of skating maintaining the spiral (3 seconds hold
before and after the change)
5) Free leg in a total split position, one or both arms hold possible
6) Holding spiral position (without any interruption) for 6 or more seconds without changes in
Spiral Sequence Variations
Simple Variation- A spiral position with limited leg and arm movement, e.g. bending of the free leg, bending of a skating leg, changing arm position, turning of head (all of these not affecting the main body core position and independent from skating edge or direction). A simple variation does not increase the Level.
Difficult Variation- These are variations that affect the main body core position and balance, e.g. twisting the upper body, bending or pulling the upper body towards the skating leg, obtaining the Biellmann position. Only these variations can increase the Level.
Please consult the ISU Technical Panel Handbook- Singles Skating for clarification of guidelines for obtaining Levels.
