As the dance moves escalate, the overlap spaces out but the margin of the overlaps bridge closely as the dance moves slow down. The one year old baby is also consistent with the baby rapid moves owing to maintain balance. But in this case, the overlap I not as rapid as the one exemplified by the ballet dancer. The baby limbs are trying to acclimatize to movement while on the other hand, the dancer has developed stable gait. The drunkard has unstable and inconsistent gait. That explains the varying overlaps. In this case as he walks the overlaps bridge a bit but spaces out as he moves fast (perhaps almost falling but maintaining inertia). The overlap is medium, not as slow as the baby taking the first steps and not as rapid as for the dancer.
On the second discussion, as I bounce the ball, I would incline and turn my head to underline the rapid moves I make owing to precisely hit my preferred target (the dining table in this case). I would also dangle my arms and jounce my head. As I lean forward to hit the ball I would walk forcefully and make strong gestures as I pick the stable ball. I would also lean forward as I pick the dropped cup and fallen books and tilt my head as I place the cup and the books back to the table. I would also dangle my arms rapidly to avoid being hurt by the chair as I bounce the
