Representative convex hulls from each element pair group with the minimum (best case), median, and maximum (worst case) relative deviations. The pairs of elements are from groups 1-3 and groups 5-7. Convex hulls containing only elements from groups 1 and 7 in the first element pair group are excluded (complete set shown in Fig. 5).
