Same start, same number of steps. Steel-blue = resample a direction every step (H=1) — it jitters near the origin (displacement ∼ √n). Teal = resample only every H steps and commit the rest (displacement ∼ √(nH)) — it reaches the outer ring. Q-chunking doesn't touch the support; it makes the RL signal usable — temporally coherent exploration instead of per-step noise that cancels itself out.
