unless i've misunderstood the technique described, i don't believe that references to all the actors between the hip and those actually used in the conforming piece(s) are necessary. i've made numerous conforming items that included only the BODY, and the parent of the first actor and the child of the last actor, and even the parent & child might not be (always?) necessary. i've already made a pair of mid-calf sandals that include only the BODY, shin, foot and toe actors. referencing the thigh was not necessary. my conforming armband included only the BODY, collar, shoulder & forearm, and my conforming bracelet included only the shoulder, forearm & hand.
