ISU Judging System
Under the ISU Judging System, the death spiral is abbreviated as "Ds" in the protocol, with the edge listed before and the level listed afterwards. The abbreviations are:
| Edge | Abbreviation |
|---|---|
| Forward Inside | FiDs |
| Forward Outside | FoDs |
| Backward Inside | BiDs |
| Backward Outside | BoDs |
A level three backward inside death spiral would be written as BiDs3.
For the 2007-2008 season, the back inside death spiral was the required death spiral for the senior pairs short program. For the 2008-2009 season, the required death spiral was the forward inside.

Famous quotes containing the words judging and/or system:
“The sure way of judging whether our first thoughts are judicious, is to sleep on them. If they appear of the same force the next morning as they did over night, and if good nature ratifies what good sense approves, we may be pretty sure we are in the right.”
—Horace Walpole (1717–1797)
“Delight at having understood a very abstract and obscure system leads most people to believe in the truth of what it demonstrates.”
—G.C. (Georg Christoph)
