Figure 2. The relative contribution of frequently recurring LCS sequences by netball playing position including centre (C), goal attack (GA), goal defence (GD), goal keeper (GK), goal shooter (GS), wing attack (WA) and wing defence (WD). The number of iterations of each movement subunit are represented by b^N, for example K² refers to KK and N⁵ refers to NNNNN.
