How pacing works: each activation = one ride entering a geofence, which queues your plays per entry. Your ad plays once a minute, rotating in a queue with other advertisers, so one ride can generate several plays. If the ride leaves your radius before they have all played, the plays already queued still run, one a minute, and nothing more is queued until a ride enters again. Impressions consumed = activations x plays-per-entry. Time blocks are even 6-hour windows; toggling one off stops delivery in that window and reshapes which passenger audiences you reach (see Audience under each radius). In Locked mode every radius stops or tiers up at its own allotment. In Shared mode, unlocked radii draw from one combined pool; hard-locked or date-locked radii keep their allotment separate.
