Best Posture
Shock triage
Treat the giant hit as a shock event. Check whether the lower ladder is still active before assuming the window continues.
A giant release dominates the day even when the lower tail ladder is otherwise ordinary.
500x+, 1000x+, or maximum-bust percentile is at least the 75th/85th percentile, without a stronger 109x-plus-giant classification.
After the giant hit, ask whether the ladder is still breathing.
