Retrospective median and interquartile spread for the selected crack-qualified chart library, sliced by class, geography, event-date shares-outstanding bucket, buildup speed, peak price, and sector. This is not the survivorship-safe runner cohort or a backtest.
Cell format: median [Q1–Q3]. Values describe this selected historical chart library only. A metric-specific N appears when missing observations make it smaller than the subgroup N.
run-up base % is base→peak. vol ratio vs base uses the clean pre-base baseline (peak_vol / mean(vol[base-30:base])). crack drop % is signed negative. peak $ volume is descriptive here and does not define a live liquidity rule.
The event-date float bucket uses historical shares outstanding as a float proxy: nano <2M, micro 2–10M, small 10–50M, mid 50–200M, large >200M. It is not strict public float; missing values remain unknown.
