Off = original (1 beat = 1 dot). On overlays lagged Poincaré pairs (RR_n, RR_n+k) so a short recording shows more dots — still real heartbeats, no invented data. Time spread staggers when each dot lights up in the video (0 = all layers flash together, higher = scattered twinkle); it changes the animation only, never the still.
