sub_82210C38 retires a line and is the only chatter function reading the rule's +20/+24 as words: node[+16] = Fluctuation * rand01 + Interval frames, state 0x20. Interval is a floor, Fluctuation a uniform additive jitter. The queue node IS the cooldown timer -- the tick counts +16 down and only then frees the slot, so the already-queued bail in sub_82210670 and the cooldown are one mechanism: a speaker cannot repeat an event until its node expires. A lingering node still holds one of the 128 pool slots. Also: +20 on the node is a ducking level, raised while a higher-priority line plays and released on retirement.
