transient: peak=18ms first_persistent=None
persistent: peak=8ms first_persistent=50
queued_bytes=40000: drain_time=32.0ms
queued_bytes=1000000: drain_time=800.0ms
Illustrative successive signal spacings (ms): [40.0, 28.28, 23.09, 20.0]
Transient trace triggers with a 20 ms interval (at 30 ms), but not with a 40 ms interval.
The persistence interval changes the question; peak delay alone cannot answer it.
