RHY.5:4.4 - Use the representation and challenge its omission
Have the intended operation carried out, or perform a bounded expert reconstruction when that is enough for the choice. Read the entrance, compare the two variants, or explain which performance changes the notation leaves open.
Choose a consequential contrast. Move the same articulation to another subdivision; keep the hand cycle while changing the spoken grouping; or retain attack positions while changing the sound classes. Ask whether the representation distinguishes what the operation needs.
Separate interpreting the expression from being able to perform it. A correct spoken reading can establish that a prepared reader recovered the positions. It does not establish instrumental technique, balanced rotation or sustained partner coordination.
