The arrangement of the stats around the circular axis is arbitrary - adjacent stats not necessarily related - and so the volumes of the shapes don't correspond to any actual data. Reorder the stats on the axis and the shape and volume change completely.
They should only ever be used for two things in footballer performance data:
