 Jumps that are executed in combination or sequence are marked as a single element, with a base mark equal to the sum of the base marks for the individual jumps.However, a combination or sequence can be downgraded – marked with +COMBO (combinations in the short program) or +SEQ (combinations and sequences in the free skate) – in which case the sum of the base values of the jumps is reduced by 80%.Every spring/summer the ISU releases rule updates which include a current Scale of Values (SOV) for different types of element.
